 A pair of  two polished stainless steel oval shape ankle cuffs.The cuffs are made from 4mm thick and 40mm wide stainless，please see the different available sizes for interior length and width measurements.

These cuffs secures with a small hex screw that screws down into a small groove/hole on the locking pin on the side opposite of the hinge. Each cuff can be removed by giving the screw 1-2 turns with the included hex key. Please do not fully remove the hex screw， as re-inserting it can be a pain & it can easily be lost if dropped. 

Please be careful with the hinges on these cuffs， the hinge might pinch skin if you are not careful.
