This is a simple ring gag, consisting of a metal O-Ring wrapped in thin leather, attached to cinch straps that pull the ring tightly into the mouth, keeping it open.
The straps can be adjusted as desired, and are secured by looping one of the straps through two D-rings.
Please Note: In most cases, the inside diameter of the O-ring will be too small to allow for penetration.
Small (J204): 1 3/4" diameter
