Swarovski 2771 Flat Back Kite is part of a geometric shape family featuring three silhouettes, the Kite (Art 2771), the Trapeze (Art 2772) and the Diamond Shape (Art 2773), designed to work together. But of course they can be used individually. The Kite Crystal geometric crystal has beautiful flat top and striking tiered facets. The smaller kite is an excellent shape for nail art. Independently or with its corresponding shapes you can create detailed & creative designs. Swarovski 2771 Kite stones are made of "Advanced Crystal" and are lead free and compliant with international standards.
