Preciosa Rhinestone Flatbacks are an easy and beautiful way to add some bling to your designs! The surface of these rhinestoens are unmarred by drilled holes, prongs or settings; all you see is the beautiful sparkly surface of these crystals. Many adhesives are suitable for attaching flatback rhinestones, except the isocyanate glues (e.g., instant adhesives), any glue containing acetone, and hot glue. There are several brands of glue that are specifically formulated for bonding rhinestones or crystals to fabric such as Beacon Gem-Tac, or E-6000. Consumer Packaging is a great way to purchase a small amount of beads for the same big impact! These packages are perfect for hanging in a retail setting.
