These quality rubber restraints for the serious players!
They have a nice thick soft padding on the inside so the're comfortable to wear even 24/7 if you want. Of course the padding is covered all over in velvety soft rubber.
The cuff itself and the strap are fortified with a layer of canvas in between two layer of rubber so you cannot stretch them and pull the eyelets out or liberate yourself.
Oh and did we mention the smell??? Oh, they smell GREAT!
