Unlike silicone urethral tubes that degrade or harbor bacteria, this metal urethral plug can be boiled for complete sterilization. Perfect for male chastity play and BDSM gear.
- π§ Fully Hollow Design – Allows Urination & Long-Term Wear The entire urethral sound is hollow from tip to base, enabling natural urine flow without removing the plug. Ideal for long-term wear inside a chastity cage or as a standalone penis plug. The hollow channel also accommodates liquid play (use sterile lubricant/solution). A must-have for urethral stimulation and catheter play.
- π Flat Cage Compatible – Designed for Chastity Devices This stainless steel urethral tube is specifically sized to fit through the front hole of most flat chastity cages, negative chastity cages, and chastity devices. The flared base prevents over-insertion and secures the plug against the cage opening. Use it to enhance chastity cage experience with urethra plug sensation.
