The clear Crystal Flat Back is backed with Swarovski's patented Platinum Pro foiling offering a silver mirror like finish to enhance the sparkle of each Flat Back. The Platinum Pro Foiling is resistant to environmental damage as well as chlorine, salt water and perfume. It is also strong enough to withstand soldering and electroplating giving it unparalelled durability.
Swarovski Crystal Flat Backs are crafted using the Advanced Crystal, Swarovski's patented lead-free formula which offers the same sparkle, dependability and variety in crystal color for which Swarovski is famous.
These No Hotfix Flat Backs are designed to be attached to textiles, wood, glass or other solid surfaces using adhesives or epoxy clay. Swarovski Crystallized Glue is an excellent choice for an adhesive that dries clear. Swarovski Ceralun is an epoxy clay available in a wide variety of colors and is the best choice when attaching Flat Back crystals to a sculpted or designed shape.
