Male urethral lock (stainless steel·hollow sound·3 base rings)

A device that locks the urethra alone rather than caging the whole penis. It leaves the outside as it is and blocks the inside, which suits someone who finds being caged too much but still wants control. Every part is 304 stainless steel.

A simple build of tube and ring

The urethral tube runs straight into the base ring, so there are few parts and little surface touching the body. Almost nothing is enclosed, so airflow is good and it feels less stuffy even in summer. It weighs about 150g.

The hollow tube lets urine through

The inside of the tube is open, so urine passes out while it is worn. You do not have to unlock it every time you go to the bathroom, which makes it a design aimed at people who want to wear it for long stretches. Always apply lubricant and go slowly when inserting it.

Three rings and what is in the box

The ring is chosen from three sizes, roughly 40mm, 45mm and 50mm. The set contains one locking frame, one base ring, and one integrated lock with two keys. For the cage dimensions, please check the figures shown in the product photographs.

What to know before you use it

This is an item you live with while metal sits inside the urethra, which places it among the higher-risk chastity devices. The original text states explicitly that cleaning should be done only with mild soap and a soft brush and that household cleaners should not be used. If urethral insertion is new to you, starting with a cage type is safer.
