Flint Patina BraceletInspired by the patina found on old desert weathered automobiles, the flint patina bracelet is made using reconditioned . 22 shells and strong magnets. This patented closure comes as a double wrap, and is dyed and aged by hand in Santa Fe. Wearing two of any of the Flint Bracelets together with the magnetic clasps in alignment creates a well organized, polished style.
