Duetto Olive and Duetto Navy bracelets are Elegatto all-time best sellers. Now available in a bundle. 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.  This style unscrews using a pin and screw method to place on wrist. Once on, the pin has to be screwed back in to the shackle to secure bracelet in place. This style is not adjustable.
