Below you will find some of the most popular metal cages on the market at just $$20. Most sites sell the same items for as much as $79.99. I went to the same factory and bought direct. I guarantee them all 100%. The come with the lock and 2 keys, and a felt drawstring bag. The rings are all 50mm. Its the largest size they make, but its still snug and will lock anyone into place. The more body fat you have the tighter it is. You have to learn how to work the ring into place and get it locked. Its part of the fun. I made them $20 so they all qualify for Free Shipping.
