These restraints are a playroom essential because they fit all different sizes, and they are quick to attach to my play partner in the heat of the moment. It is nice to give them something to hold onto when I am tormenting them -Mistress Isabella Sinclaire These easy to use and durable leather restraints use the weight of their own body to cinch tight, restricting movement and leaving them helpless.

The ends have a durable trigger snap hooks that open and close easily yet hold tight during rough play. 20.5 inches in total length
