A urethral chastity cage made of steel is a type of male chastity device designed to restrict access to the penis and often includes a urethral tube for controlled urination. 

4 Rings Available and you can select the size you want: 40mm, 45mm, 50mm and 55mm.

Easy to Pee: The inclusion of a urethral tube allows for easier urination while wearing the device.

Three Sizes for the Cage: The cage itself comes in three different sizes (likely small, medium, and large) to accommodate varying penis lengths and girths. Choosing the right size is important for comfort and effectiveness.
