I have loved this design & technique since we spent 7 years living in Hawaii. We have found ourselves back by the beach on North Padre Island and I can't imagine a better necklace than a waterproof one. These have become my signature piece. This simple design is perfect for every day and any occasion - a night on the town or a yoga class. They look clean and I've never had one come off. And as they are waterproof - you can wear them surfing or swimming!
