Offered is an older piece from Coro. It probably dates from the 1940s or early 1950s. The cuff style bracelet is silver plate and is hinged on 2 sides.
The inside trademark shows a box with the word Coro written inside it in script. Below the box are the words: Patent Pending
I believe this is designed to fit fairly snug on your wrist. At it's widest point (across your wrist) it measures 2 3/16 inches. The thickness (lay the heel of your hand on the table so that your little finger is down and your thumb is up) is 1 5/8 inches. So for instance my wrist is 7 inches around. This bracelet is too tight for me. Ideally a wrist smaller than 6 inches would probably work fine.
Condition: Shines up nicely. There is a small surface dent on the very edge. The hinges all work well.
