What it says on the tin. 5/16" ID 16 gauge bright aluminum (high chrome content, no black rub-off) joins pink and blue neoprene (what they make wetsuits out of) in the Full Persian weave. This is a bangle bracelet. It's stretchy enough to roll on over your hand, and will be loose on your wrist, but will stay on most adults. Roll it one way to show off the silver, the other way to flaunt the colors.
