The Hardware Nail & Screw silicone sounds from the Master Series offer two magnificent shapes for your penetrative penis pleasure. Both urethral sounds are designed like heavy hardware, teasing you with a spiral-textured screw and a smooth, hexagonal nail.

This insidious duo stimulates your penis from the inside and offers you a unique sensation that feels truly amazing! The flexibility and suppleness of the high-quality silicone material make for a comfortable insertion as it conforms to the inner curves of your body.

We recommend that you use a high-quality water-based lubricant in your play. The sound bars are hypoallergenic and are easy to clean with warm water and a mild soap.
