These bracelets are made of 100% recycled copper, new brass (gold tone) or sterling silver, that we have forged and hammered into cuff bracelets. They are pliable and can be formed to fit perfectly on wrist sizes from 5" - 8". Sleep in them, shower in them and stack them! Copper bracelets have long been proven as an effective healing aide for joint pain and inflammatory issues as well as overall balance and well being. Personally, I like the cold feel of the metal as it doesn't conduct heat as easily as other metals. The cooling on the wrist helps with carpal tunnel and helps you feel grounded and balanced. Add a kick ass mantra of your own custom quote or saying and you will have a perfect every day bracelet!
