Decorate the fastest, easiest way possible with Swarovski hot fix crystals. Swarovski's trademarked, patented hot fix glue is on the back of each flat back crystal we sell. You've seen thousands of these crystals on Olympic skating costumes, on gowns at Hollywood red carpet affairs, at Disney, Mardi Gras, Cirque du Soleil, and Las Vegas shows. They're used on quilts, costumes, shoes, accessories, jewelry, polymer clay, wood, home decor, paper, velvet, lace, spandex and much more. Apply with the BeJeweler in seconds and wear or use immediately (no yucky mess or waiting for the glue to dry). Permanent on porous surfaces. Having trouble picking a size? Click here for help!
