Each grommet is hand cut from sterling silver tube and is hand riveted to the natural (real) crocodile backstrap leather. I then line the inside of the bracelet that lays against your wrist with natural lamb leather. I hand fabricate every part of this bracelet (except for the magnets). There are absolutely no manufactured parts on this one of a kind authentic crocodile backstrap black leather bracelet. The bracelet features a magnetic closure. 7 inches in length. This bracelet is a prototype that I have decided to keep in my personal collection. I can make a similar design upon request, email me.
