Duetto bracelets bring inspiring memories of afternoons on the bay. They are made of double nautical nylon cords for strength and durability, with the 316L marine-grade, silver plated, stainless steel shackle fastener polished to a high shine that won't blacken or tarnish. The branded shackle makes putting the bracelet on effortless. Hypoallergenic, waterproof, and fast-drying, the hard-wearing nylon will not fade over time.
