What our customers say

4.8(5)

The recurring praise is for the material quality, the colours, and that double knot shape, plus customer service that fast-tracked a replacement and threw in a freebie when something arrived torn. The one honest snag people keep flagging is the size, several wished it were longer, so do verify the measurements before ordering.

Le manchon de balle Geeyem

Name: Le manchon de balle Geeyem
Brand: Uncover Creations
SKU: GEEYEM-XSML-SLEEVE
Price: 29.00 GBP
Availability: InStock

£29

Stretchy silicone with subtle nubs and a double knot ridge, designed to translate your bullet's buzz into something you actually feel travelling along all those waves. It's compact (genuinely, check the measurements before you fall for it, we love it but it's a wee guy), and made from body-safe silicone so the only thing it's doing is its job. The alien finish is pretty enough that you'll be tempted to display it instead of using it (please use it).

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!

Shipping to Royaume-Uni

Discreet Shipping

All our toys arrive in the most boring brown boxes imaginable. No logos, no winking emojis, no hints. Just you, your package, and absolutely zero awkward small talk with delivery drivers.

Returns

Look, we get it. Sometimes things don't work out. We've all been there.

You've got 30 days from when your package arrives to decide if you want to return something. Just make sure the item is in the same condition you received it — unused, with all its original packaging and tags intact.

For more info here's our full returns policy.

Secure Checkout

We accept credit cards, debit cards, PayPal, ClearPay, Sezzle and Klarna. All secure, all simple, all showing discreetly on your bank statement.

Those little nubs and the twin knots give the vibrations something to push against, so the buzz spreads out across the texture rather than staying in one polite spot.

The stretchy sleeve hugs most standard bullets, so you keep your own controls and just upgrade the shape (works with our Bullet Vibrator or the Nu Sensuelle if you're starting from scratch).

Body-safe silicone, rinses clean in seconds, and discreet enough that nobody clocks it for what it is (they'll assume it's modern art).

A new favorite

This was my first order ever from Uncover Creations and I can say confidently it won't be the last! The Geeyem bullet sleeve is just perfect 🩵

- size: default (it's a bit small because it's a bullet sleeve, I really really want to get a bigger one next time, because that double knot shape is amazing, not to mention all those little nubs)
- color: surprise me premium (I'm SO happy with the result, so pretty and alien-y, I lowkey wanted to put it on a shelf when I got it)
- firmness: went for medium as I really wanted to FEEL the vibrations. Do not regret that choice at all, especially since, again, the toy is not that big.
- I added a Nu Sensuelle bullet, which doesn't disappoint, except maybe for the battery - but it's not that bad.

Alien kink unlocked 🫶 Also, it came with a lovely mystery tentacle dildo, and I couldn't be happier! The color is so cute, I'm in love 💜

Regarding Uncover Creations, everything was quick, secured and my order easy to track. I can't wait to order again!

Cute litte guy

Great quality material, pretty colors, just so small... lol It's my own fault for not verifying measurements

Great toy, great customer service

Received a toy that had a tear in it out of the bag, which was rather disappointing, but I e-mailed them about the issue and they immediately priority shipped me a new replacement toy, and even included a free small plug as well! Very fast customer response and service, and the new toy works great, thank you very much!

Thought it be longer 😅😭

Best custom company out there and Amazing customer service when I had a difficulty with my product. 10/10

Product FAQ

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.

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.

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!
