Whimsically bold and modern jewelry by Iris Isaacs is a statement piece sure to catch attention! The necklace is made of hypoallergenic stainless steel, and neoprene rubber cord that the pendant's end seamlessly fits into. To open the necklace, hold the rubber at the end of the cord and pull it away from the stainless steel (as opposed to stretching the neoprene itself). If length shortening is required, simply cut the neoprene rubber with scissors. The pendant measures 2.5in long x 2.75in wide and comes with two rubber cord lengths. Handcrafted in Australia.
