This handcuff ring is an exact replica of a real handcuff, and it even works like a real one as well!  We made one change though; we made it to bottom out on a specific ring size so that it would not clamp on too tightly.  Inserting the tiny key and turning clockwise will open the cuff.  The key can be worn on a necklace, or it could be on a chain attached to the ring.  The entire ring and key are crafted from aerospace grade titanium.

The ring shown was made in a size 10 and the finish is polished.
