These comfortable cuffs are made of soft and sturdy leather. Because the buckle is easy to adjust, the cufs are easy to put on and adjust in size. You can remove the chain between the cuffs so that you can attach ropes or other accessories to the rings. You can also close the buckles by attaching padlocks to the hooks. Locks are not included as standard. Adjustable from 22.8 to 30.5 cm with a diameter of 5 cm.
