I want to find a set of leather wrist cuffs but I've a specific design in mind. I want a metal ring to bisect a leather strap around my sub's wrists... similar to this collar or this collar. I've peeked at local shops and asked around but can't seem to find what I want. Before I comission someone to make them for me, have any of you seen wrist binders such as what I've described? If so, where?
