V3 stainless steel chastity cage (integrated lock·2 keys)

A smooth tube-shaped stainless steel chastity device with closed sides. The specification table in the product photos divides the cage into four sizes, listed as Nano 82mm, Small 97mm, Standard 102mm and Maxi 110mm, with a second measurement of 20mm, 45mm, 52mm and 61mm given alongside each size.

A tube that curves with the body

Rather than a cage woven from bars, it is a single continuous tube, so the outside is smooth and there is little to catch on clothing. It curves downward along the line of the body, which makes it press less when you sit. A hole is pierced at the front end for urinating and for washing.

Four rings and the lock in the joint

The rings come in four sizes, 36mm, 40mm, 45mm and 50mm, and they are curved to wrap the base. A groove at the top of the ring takes the cage, so the lock sits inside the joint rather than hanging outside. The keys come with it.

What to know before you use it

The supplier gave no written description, so the material and the contents are described only as far as the photos allow. Closed sides look tidy but give little ventilation, which can feel stifling in summer. Metal has weight, and the size you pick from the specification table matters more than anything else for how it wears.
