This amazing set is bound to get everyone's attention. This sleek design incorporates a locking mechanism which uses a padlock literally built into the item itself.There has been no expense spared in the making of these, as they're made entirely of stainless steel with a brushed finish (other than the brass padlock). This is instantly discernible from the chrome plated metals which other sellers try to pass off as being stainless steel! The wrist and ankle cuffs are available either circular, or as an oval,so you can choose the style which is best for you.
