Size Guide

Full details

Our first grinder where you actually get to pick the size (took us long enough, honestly).

A brand new design that follows on from the original Oni Grinder (related, not twins, please stop asking if they're the same). The face does the work here: carved brows, fangs framing a wide open mouth, then a textured tentacle tongue sitting right where you want the attention. Bumps, ridges, the lot. The horns are mostly there for drama.

Round the mask runs a floral frame with strap slots built in, so you thread the nylon straps through, click the quick release buckles shut and fix it to a pillow, a thigh, whatever's closest (choose wisely). It stays put so you don't have to.

Body safe platinum silicone, poured made to order. Small, Medium or Large. You choose a size when you buy a dildo, so why should a grinder be any different. Add the vibrating bullet if you fancy a hum.

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!

Thread nylon straps through the slots in the floral frame and snap the quick release buckles shut. Pillow, thigh, wherever, it holds its ground.

Body safe platinum silicone, made to order in Small, Medium or Large. Warm water and mild soap keep it fresh between rides.

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 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.

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!

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.

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.
