You'll love these beautiful lime green, blue and black bracelets that have just enough sparkle! They are very comfortable to wear and flexible - I think they are silicone but am not sure. Wear one at a time or bundle them together or with other bracelets. BUNDLE TO SAVE MONEY: When bundled you only pay one shipping cost up to 5 lbs. It's like getting up to $6.49 off each additional purchase added to this bundle or FREE shipping on the extra items. It's a WIN-WIN for you and me.
