## Emma's take

Stick it anywhere. Both hands free.

Freedom is a smooth wall, a stable floor, and both hands exactly where you want them. This suction cup attachment is Tantus's own ultra-premium silicone, the same body-safe formula behind their toy line, and the improved base grips any smooth surface without wobble or drift. Compatible with Tantus, Vixen, and Topco bullet toys, it turns any supported toy into a fully stationary experience.Reviewers consistently note the improved base holds firm through vigorous use. Water-based lube only, skip the silicone.

## Frequently asked questions

## What surfaces does the suction cup grip securely?

It works best on smooth, non-porous surfaces: tile, glass, sealed wood floors, acrylic tub walls, and most laminate. Textured, rough, or porous surfaces won't hold a reliable seal.

## Which toys is this attachment compatible with?

It's designed for Tantus toys with a compatible base, and it also works with Vixen and Topco bullet vibrators. Check that your toy's base fits the cup diameter before mounting.

## Why can't I use silicone-based lube with this attachment?

Silicone lube can degrade the surface of silicone toys and accessories over time, affecting both the material and the suction grip. Water-based lubricant keeps everything in good shape.

## How do I clean the suction cup attachment?

Warm water and mild soap before and after use. Rinse thoroughly, press out trapped air from the suction base, and let it fully air dry. Boiling is safe given the 100% silicone material.

## Can this be used in the shower or bath?

Yes. The silicone is fully waterproof and the suction cup grips smooth wet tile or acrylic. Press it firmly and give it a twist to lock the seal before use.

## Is this attachment body-safe on its own if it contacts skin?

It's made from Tantus's 100% ultra-premium silicone, the same non-porous, body-safe formula used across their toy line. No plasticizers, no phthalates.
