The Rapier LKM-031 is a polished 304 stainless steel chastity cage built around a forward threaded urethral tube with a removable spherical tip. Choose catheter size S, M or L and a 40, 45, 50 or 55 mm base ring.
Threaded Urethral Tube
The metal tube uses a threaded exterior for pronounced sensory stimulation and a removable ball-shaped end shown in the gallery. The open steel frame provides visual access while the tube and base ring create the Rapier’s distinctive restrictive configuration.
304 Surgical-Grade Steel
The premium 304 surgical-grade stainless steel is rust-proof, hypoallergenic and built for lasting wear. Its high-gloss, vacuum-polished surface is smooth, burr-free and designed to follow the body without irritation when correctly sized and used.

Urethral Use and Care
Urethral products are intended for experienced users. Use appropriate sterile-care practices, never force insertion, and do not keep the passage obstructed. Stop immediately for pain, bleeding, numbness, swelling, unusual discharge, discoloration, fever or difficulty urinating, and seek appropriate medical help when needed.
Clean the cage, tube, removable tip, ring and lock thoroughly after use and dry every component completely. Orders ship in plain, unmarked packaging.
