Made popular by surfers, Polyester Cord is virtually indestructible. Unlike leather, it can stand up to harsh ocean water (or chlorinated pools). Available in two sizes, 1mm and 1.5mm, it is the preferred cord for wrap bracelets or necklaces when your jewelry will be exposed to the elements, including sweat, water, or extreme weather. Plus, the ends can be sealed with a flame and it’s easy to weave or braid. Very similar to round woven cotton, Surfer Cord is even more durable.
