A lock for self-bondage

This stainless steel padlock serves as a time limiter for self-bondage practices. Pour water into the padlock and leave it to freeze, then hang it up and place the key to the handcuffs underneath it, so that it falls within easy reach. At a room temperature of 25 degrees, it will last for approximately 100 minutes.

Although self-bondage is completely outside my area of interest, I’ve read a bit about it and spoken to a few people who are into it. I hope this lock finds a buyer.
