This unique, one-of-a-kind piece is in excellent condition and comes with a detachable wrist lanyard. I believe the silver trim is sterling but I cannot find a sterling marking. The hinge works perfectly and the clasp is nice and tight. Please view the photos, they add to the description. I've done my best to picture and describe everything, but if you have any additional questions, I will try to respond promptly. Buy with confidence...you will not be disappointed.
