This impressive steel hook can be hooked up to ropes and other bondage equipment, making sure it keeps a strong hold on its wearer. There's 5" of insertable length (the ball and a portion of the hook). The hook then rests against the back, while the ring (1.5" in diameter) is used to connect to ropes.
First time I had ever heard of it when my partner said he wanted one. Apparently he knew what it was and how to use it. All I can say is WOW! Different, smooth, straightens your back when you use it. Loved it and can't wait to use againAnonymous - January 19 2016
