The adjustable sizing and the fact that they are easy to put on a take off has made these a best seller! They suit a variety of jewellery styles so if you are buying for yourself or for a gift, this is a great choice. They look fabulous stacked with beaded bracelets or other bracelets but also look great on their own. There are 3 options to choose from! The chain is stainless steel. This bracelet will fit most!
