Der Coral Keeper Grinder

We use super soft (00-40) or squishy soft (00-20) silicone on the shore hardness scale, giving our grinders that perfect, bouncy feel. Our experience has shown that folks usually love the softer side of things, so that's our go-to. We can also pour them in medium (10A) if you're into a firmer experience, but this needs to be a special request through our customer service team.

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!

We offer the ability to upgrade your grinder with a silky smooth finish. To achieve this silky smooth finish, we use an additive derived from Durian tree nuts, ultimately resulting in a more luxuriously smooth feel that glides rather than grips like other silicones.

However, we recommend you avoid the silky smooth upgrade if:

1. You are allergic to durian, tree nuts and tree nut derivatives or musk thistle seed
2. You are sensitive to smell - Normal silicone has no scent however using silky smooth will give the silicone a subtle, nutty scent.

The super silky upgrade is only available on our sex toy grinders and both of our made to measure penis extenders.

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.

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.

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!

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.
