These beautiful flatbacks are perfect for adding sparkle to scrapbooks, flip-flops, clothing, greeting cards, cell phones and more! Their relatively small size means they can go almost anywhere. Please note that when using flatbacks, you should never use a glue gun or super glue (cyanoacrylate) as they will damage the foil backing on the rhinestones. Also be aware that while flatbacks are terrific for adding sparkle to clothing they should never be dry cleaned.
