Cobra Series Mamba Chastity Cage | F312A Small Size - Golden

The Cobra Series Mamba is built for men who want steady control without giving up comfort.  It wraps your cock in a smooth, flowing shape that feels natural on the body and easy to live in, even for long wear.

Inspired by the calm strength of a snake, the cage follows soft curves instead of sharp angles.  It doesn’t crush or pinch—everything is held gently, keeping erections under control while letting you move, sit, and breathe with ease.

Made from solid stainless steel with a polished gold finish, the surface feels cool, clean, and slick against the skin.  Small curved openings along the cage help air move through, keeping things dry and fresh throughout the day.

This cage comes in three sizes—Small, Medium, and Large—so you can choose the fit that works best for your body.  You can also pair it with different rings or support straps for extra security, depending on how locked you want to feel.

The Mamba is not loud or flashy.  It’s smooth, controlled, and confident—made for men who want real chastity they can trust, every single day.0
