This is a set of velcro-strap wrist cuffs and thigh cuffs, along with two snap hooks to connect to the o-rings on the cuffs.
The cuffs are strong enough to hold, but easy enough to escape if the need arises.
When the wrists are fastened to the thighs, there is still enough play to allow access to private parts, so part of the game can be having the prisoner play with themselves for your viewing pleasure.
What I like about this set is its versatility. For example, the wrists can be bound to the thighs behind the back, or can be crossed in front. The thigh cuffs can be wrapped around the ankles in a double wrap, and the wrists then connected to the ankles in a quite accessible position, either forward or reverse.
The only reason I have not given this five stars is that the cuffs are a bit thin, and serious bondage enthusiasts would find them elementary.
But I can tell you that it has has quite an effect on my girl whenever I bring it out.
