This is a unit of 5 exquisite genuine Swarovski Cosmic 10 mm AB beads, which are now a discontinued item with Swarovski. These beauties can be used to create your dream catchers, sun catchers, necklaces and bracelets. I bought these in a lot for my crafting and have a few in excess available for purchase. They are a unique shape and photos do no justice for these sparklers. They will splash rainbows in a room when the sun highlights them and in evening hours will continue to twinkle due to the AB finish they contain. A must have for a crystal lover or crafter.
