When I heard about the story behind these, I just couldn't resist! 2 kids started a bracelet charity to help feed, clothe, and give hygiene kits to the homeless in Dallas, TX. These bracelets are made from real stones AND they are DIFFUSER BRACELETS. One of the stones, is a lava stone (black bead). Put one drop of your fav essential oils on the lava stone (black bead). Your wrist is a pulse point so these are perfect for all day wear and you are supporting a great cause!
