At Artbeads.com, our copper chessboard crystal is a favorite among our rhinestones. SWAROVSKI ELEMENTS Austrian crystal is always the best choice for your accessory designs. Our geometric square cut is perfect for maximum sparkle. Add the warmth of the copper tone to your purse, shoes or even a lamp with beads and findings that you love! 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. Please follow the cleaning care instructions on your glue; many glues require that clothing be air-dried. If you do machine dry always turn the article inside out before being placed in the dryer to avoid damage.
