Swarovski Butterfly Long Necklace I love sparkly things, and I especially like Swarovski. The adjuster is about 20cm long, so you can adjust it to your preferred length. Swarovski crystals are scattered around the butterfly, as if to say, "Here they are!" Necklace size: 68cm (adjuster 20cm) The necklace box is missing, so it will be shipped in a bracelet box. Therefore, I am offering it at a slightly lower price, making it a great deal.
