Heavy Leather Neck and Hand Restraints with Belt

If you want to restrict the hands' movement very much:

This versatile adjustable back cuff made of sturdy cow split leather (2.1 to 2.3 mm thick) is made of a collar and a waist belt, which are connected with a longitudinal strap. The two handcuffs are attached to the waist belt with metal rings.

Both the collar and the waist belt are adjustable at the front with buckles.

Sorry, the shown thong is not included.
