Soft Flex Extreme 925 is the hot new jewelry wire on the market! Soft Flex Extreme, which is sterling silver over steel and nylon coated, adds that special touch to any jewelry design. Perfect for floating necklaces. String several strands together with a pendant for a simple design that will leave an impression! This is a 19-strand, silver-plated product and is not as flexible as regular Soft Flex. It is likely to kink with improper use. May not keep its shape with very light beads.
