Swim, sweat and shower in it, and it still looks new. Every piece in this collection is made from 316L stainless steel, which means it is fully waterproof, won't tarnish and won't rust no matter how often you wear it. No need to take it off at the gym, the beach or in the rain. This is jewelry made for real life, designed in Sweden and protected by a lifetime warranty, with free shipping across Europe on orders over 35 euro.
