Our Natural Stone Bracelet is 100% handmade. It is hand woven with parachute rope, which is resistant against water, sweat, and  parfum. So you don't have to take your bracelet off when you take shower, bath, swim or at the gym. It is not to be mistaken with rubber bracelets which can break away easily! Nevertheless we recommend protecting the stones from such factors considering the sensitivity of each stone which can be different.
