These liners are made of leather, and make for a long time that handcuffs can be worn.
Spikes are put on the outer edges to hold the handcuffs in place so there is no slipping, and with no slipping and the handcuffs not cutting into the skin the cuffs can be worn for a very long time.
If you have handcuffs / like handcuffs then this is an item that you need in your toybag, so as to stop any complaining that might occur.
They come in a set and are put on as the handcuffs are put on.
The liners come in 2 different sizes, this particular one is for a larger wrist.
