Rubber (neoprene) is a favorite choice of our customers. It is so versatile! It is available in bright colors and even white. It is also available by the foot, so you choose your length. You can pair it with sterling silver because, unlike natural rubber, neoprene does not burn or tarnish silver. We at Artbeads.com love the many jewelry design choices we offer with our vast selection of beads and pendants and supplies, just like this one. The neoprene rubber material is latex-free, so it's safe for anyone to wear!
