This is for the intermediate user of a cock cage. This will likely allow you to wiggle out if you really wanted because it is fairly comfortable. Perfect for those needing a lock and key. Also perfect for those who want to keep the key in hand. Slip out without permissions and you will not get back into it without needing the key....! This means that you can be comfortable locked and checkup on. The rings consist of three interlocking pieces that fit together. The oval locking pin goes through the middle recessed hole connecting the cage portion to the ring. Assorted size rings included in your kit allowing for a custom fit. Use for restricting access to your chronic masturbator. !!!!
