In a controlling kind of mood? Send your sub straight to dick jail with the Master Series' Cock Cuff Snap-On Chastity Cage. 

This nearly solid (there's a pee-hole and some air vents) aluminum Cage fully restrains their shaft and tip. You'll lock it up tight to the adjustable snap-lock base ring before letting them say bye-bye (if you feel generous) to the cock you now own.

A key for the built-in lock is included—keep it (or make sure your key holder keeps it) in a safe place.

The Cock Cuff's slick surface is easy to clean with soapy water or a favorite toy care formula.

Cage length: 3.25'/8.3cm, Cage width: 2.5'/6.4cm, Cage height: 3.5'/9cm, Base ring: adjusts from 1.6-2'/4-5cm
