What our customers say

5.0(20)

The recurring story is almost suspiciously consistent: first grinder, mild hesitation, immediate conversion, followed by wishing they'd started sooner. Reviewers keep praising the softness of the texture, the colours, the reaching insertable horn, and how the slow buildup delivers, with several calling the bullet option worth every penny. The one honest flag: on thinner pours the bullet can occasionally pop out.

Der Coral Keeper Grinder

Brand: Uncover Creations
SKU: CORALKEEPER

Flowing ridges underneath you, a curling insertable horn doing its own thing at your entrance, and the kind of slow buildup that makes vibration feel like it was rushing you. If you suspect a grinder sounds better in theory than in practice (a fair worry, we had it too), the body safe silicone is so soft that all that texture teases rather than overwhelms, even on the most sensitive bits. It's also our first insertable grinder, which felt like an oversight worth correcting.

Full details

Wir präsentieren den Coral Keeper, unseren ersten einführbaren Grinder! Verziert mit fließenden Noppen und liebevollen Details, verfügt dieser Grinder über ein einführbares Horn, das Ihnen exquisite Stimulation bietet, während es Ihren Eingang neckt und erkundet.

Der Coral Keeper wird mit zwei schwarzen Nylonbändern (je 1 m lang) mit Schnellverschlüssen geliefert. Sie können ihn einfach an einem Kissen, Ihrer Hand, Ihrem Oberschenkel oder Ihrem Unterarm befestigen und so die Nacht komfortabel und lustvoll verbringen.

Wir empfehlen Ihnen, eine ordentliche Portion Ihres Lieblingsgleitmittels zu verwenden, um ein besonders leichtes Gleiten zu gewährleisten. Und wenn Sie ein noch glatteres Ergebnis wünschen, rüsten Sie Ihren Grinder mit unserem Silky Smooth Upgrade auf.

Seidig-glattes Upgrade
Wir bieten Ihnen die Möglichkeit, Ihre Mühle mit einer seidenweichen Oberfläche auszustatten. Um diese seidenweiche Oberfläche zu erzielen, verwenden wir einen aus Durian-Nüssen gewonnenen Zusatzstoff. Das Ergebnis ist ein luxuriös glattes Gefühl, das sanft gleitet, anstatt wie andere Silikone zu kleben.

Wir raten Ihnen vom Upgrade auf die seidenweiche Oberfläche ab, wenn:
1. Sie sind allergisch gegen Durian, Baumnüsse und Baumnussderivate oder Moschusdistelsamen.
2. Sie sind geruchsempfindlich - Normales Silikon ist geruchlos, die Verwendung von seidig glattem Silikon verleiht diesem jedoch einen dezenten, nussigen Duft.

Dieses Design entstand in Zusammenarbeit mit Frost, einem talentierten 3D-Künstler, der in der unabhängigen Spielzeugszene für seine herausragenden Arbeiten bekannt ist.

Platinum Silicone

We use platinum-cure silicone for every single product because honestly? You deserve toys that are safe, durable, and feel as good as they look.

What makes it so special?

It's non-porous, which means when you clean it, it actually gets clean clean. No sneaky bacteria hiding in microscopic crevices. No weird smells developing over time. Just pure, body-safe silicone that stays hygienic no matter how adventurous you get.

Plus, it feels incredible. Like, genuinely fantastic!

It was love at first sit

PhallophileReviews.com

Super soft bumps for the grind, a reaching horn for the inside, and a pace that takes its sweet time getting somewhere very good. Pairs beautifully with the bullet vibe option, or stands entirely on its own.

Two 1m nylon straps with quick release buckles mean it mounts to a pillow, a thigh, a hand, or a forearm (or a willing partner, who is now furniture). A generous dose of lube and you're off.

Body safe silicone with no scent to speak of, which surprises people who expect a whiff and get nothing. Washes up easily with warm water and mild soap, and pairs well with a good water based lube so you decide how much and when to top up.

My first grinder and I was surprised

My first grinder and I was surprised.
Ive never used a grinder before so I was skeptical if it could get me where I wanted to go. I went for the silky texture because I thought if I didn't like it I could still use it as a fidget. The first few tries were clumsy, I wasn't really sure how to go about it. I strapped it to a pillow that I specifically use to attach toys to--and it gave me a workout ngl (i should work out more). ANYWAYS, then I slapped it to the floor and tried there (more successful without getting as tired). I got a bullet to insert inside and the rumble didn't change the experience much (but im also someone that feels more with direct stimulation rather than rumbles).
Cleaning was easy! I got the foaming cleaner, and there's not a lot of tiny crevices to scrub into.
I've never bought from this company before, and I am quite pleased!

Second grinder.

Purchased my second grinder after enjoying the first so much. This one, is only 2/3 as thick as my first, and as a result, the bullet sometimes pops out. Other than this, it is very enjoyable. Keep them coming.

Perfect duo

I've always wanted to try out a grinder but could never find anything that looked comfortable enough.
I had to buy this when I seen it! I am very picky with toys but reviews sold me on it straight away.
I went with the basic options and without a bullet.
The texture is perfect and super soft as described. The colour is exactly what I would have wanted even though it was a surprise.
The free mystery dildo, I was slightly worried about before it was delivered as I knew it would be 'small' but didn't want to upgrade to any bigger incase it was too much 😅
I was pleasantly surprised when I unboxed it, it's the perfect size and I love the colours.
Already my favourite toys and I've not even had them for 24 hours.
Shipping was fast, so I am overall very happy

So Delicious!

I think some grinders are missing a bit of protrusion, but not the Coral Keeper! That reaching "claw" feels so great for external or internal play with some of the most gorgeous, detailed molding I've seen in my collection of fantasy toys. And it feels so freakin' fantastic!

A 'grinding-ly' good time

I'd never tried a grinder before but I honestly wish I had tried one sooner ! This is so much fun and with the bullet as well ... I possibly need to apologise to my neighbour. I really like the softness (super soft) and the colours are just so pretty ! Looking forward to trying it on a firmer surface and seeing how that plays out - it will be fun regardless ! The insertable length is also a bonus and is a fun stimulation, alongside or without the bullet. For a beginner in some aspects of all this, this has definitely been (for me) the perfect introduction to grinders !

Also want to shout out a big thank you to Jade - I originally contacted the team for advice, as I'd had issues with the small size ovipositor (not their fault but it's too big for me to have fun with personally) and I was really worried about what to try next, in regards to a fun toy which was also insertable. Jade didn't make me feel embarrassed and actually provided me with several options on grinders, both with insertable parts and without, as well as taking into consideration the length of the insertable, so I could actually have some fun ! 10 out of 10 for the grinder and 11 out of 10 for Jade and the team - thank you <3

Better than I could have imagined

Took a while to reach the states but worth the wait and appreciated the team at uncovercreations updating me all along the way. Love the colors, the level of firmness, and was super surprised there is no oder. Might get another one in the future.

Cunningly wonderful…

I love grinding but this was my first official grinding toy… and I’m over the moon with it. Tried it strapped to my partners leg and solo to a pillow… hits all the right spots. I went for the medium and surprise me colours, I like it hard and the grinder did not disappoint. Would recommend.

Incredibly versatile

First experience with a grinder, added the bullet vibrator and found a way to turn my partner into a sybian for cheaper. Can't wait to experiment more with it!

Amazing! Better than I imagined

Loved the color! Super soft and silky! I was so excited to try it! Very much met my expectations! Highly recommend!

Stunning!

Absolutely gorgeous, so soft and pliable, and the insertable horn hits just the right spots. Worth the wait!

Beautifully made and very sexy

Thank you, I love this and look forward to using it a lot ♡

amazing good lord

holy shit this hits so incredibly different after being used to vibration, the buildup was amazing, and I'm sure that the extra soft claw would feel even closer to a tongue, 10/10

Beautiful creation

My first purchase of many I imagine. Beautiful colours and loved receiving the mini (tempted to buy the full size).

Amazing feeling

This is my first time trying a grinder so I wasn't sure I was gonna like it... I was still, doubtful, until I poured a good amount of lube on it and FUCK. Now I get it. Excellent. It's super soft so even with a lot of texture on sensitive parts it doesn't hurt one bit, and the ridges just feel amazing.

can't stop cumming

fucked myself absolutely stupid on this twice as soon as it arrived. gonna do it again soon.

The toy you never knew you needed

This is an extremely satisfying toy. I use it often and the grind leads to an intense buildup for orgasm.

Take aways:
I bring mine to play parties and many people are in awe and want to know where I got it.

It makes a squishy sucking sound with lube and turns me and others on.

I got the super squish, with bullet hole and silky texture, no regrets. The nutty musk smell is intense at first but fades to a lighter scent after many washes. Just break it in before introducing it to others.

Just purchased another model to add to my collection! They also sent me replacement bullet when mine died under a year. Top tier customer service.

Amazing product - buy it!

Very impressed with my purchase as well as the shipping. High quality products. 100% recommend.

Fantastic product

Absolutely amazing product, I’ve never felt the durian silky texture in the silicone but dang, I’m sold!

Great grinder!

This grinder is amazing, I was hesitant about it at first, thought it would be a fun idea but maybe not as great in practice. I was so wrong!! I enjoy riding this thing almost more than D, the vibe option is 100% worth it 👍❤️

Fantastic product and great customer service

Product FAQ

What are grinders?

Sex toy grinders are specially designed toys with textured surfaces meant for grinding and external stimulation.

They're made for creating delicious friction against all your favourite external spots, whether you're rocking solo or turning up the heat with a partner.

For vulva owners, it's like having the perfect "on top" moment whenever you want it. And penis owners? Roll it up and you've got yourself a texture-tastic pleasure party!

Why are we so excited about grinding? Because sometimes the simplest pleasures are the best ones! We're bringing back that natural, intuitive way of feeling good that somehow got lost in the shuffle of "traditional" toys.

The best part? There's no wrong way to groove with a grinder. Whether you're flying solo or adding some spice to partnered play, these toys are all about finding your rhythm and owning your pleasure.

What is the vibrating bullet upgrade?

Do you want to take your grinder to the next level? Well, look no further! You can now add a hole and a Remote Controlled Vibrating Bullet right into the base of your grinder. Boom! Instant Vibrating Grinder!

We've even made sure that the hole fits most bullets perfectly, so you can use your own bullet or ours. Get ready for a grinding experience like no other and feel those intense vibrations all over your grinder!

What is the silky smooth?

Silky Smooth has been retired from our finish lineup (we only keep what we can deliver the same every time). For that same smooth, glidey feel, pair your toy with a good water based lube. Bonus: you decide exactly how much and when to reapply.

What are the different colour options?

We offer 6 different colour styles, though not all are available on every product.

Surprise Me Basic - Leave the decision in our capable hands and we'll choose a solid colour that compliments your toy selection.

Surprise Me Premium - Leave the decision to us and we'll get creative with two or more colours. We love this choice as it allows us to get experimental with all of our colours, often resulting in our best pours.

Solid - One colour that will run evenly throughout your toy

Fade - Two colours combined that are gradually blended together. Colour 1 will be the tip of your toy and Colour 2 will be the shaft and base.

Marble - Two colours combined resulting in a veining effect similar to classic marble.

UC Trademark - This is a product-specific colour. The main image of the product is the UC Trademark colour.

For more information, take a look at our colour guide.

Why do you only use platinum silicone?

We use platinum silicone so you get a toy that is non-pourous (meaning when you clean it, it gets fully clean and can't transmit bacteria), doesn't smell, is body safe and feels fantastic.

If you'd like to learn more about cleaning your toys, read our sex toy care guide.

What do the colours actually look like?

Check out our colour guide to see exactly what our colours look like. But please keep in mind, each toy is hand-poured, so no two are exactly alike!

Do the grinders come with straps?

Yes, the grinders do come with straps! Each one includes two black nylon straps, each 2.5ft (0.7m) long, with quick side-release buckles. You can strap it to a pillow, your hand, thigh, or forearm for hands-free grinding fun.
