In sync design necklace pod material 100% hypoallergenic stainless steel, black neoprene rubber, 22ct matt gold plate size drawing – 80 x 25mm (3.1 x 1.0 inch), necklace – 130 x 160mm (5.1 x 6.3 inch) available in either natural stainless steel or powder-coated black ‘drawing’ that extends into a flexible black neoprene tubing to create a continuous line the whole way around. Each necklace comes with short and long lengths of neoprene to allow for personal preference. To open the necklace, pull the neoprene rubber from the end off the stainless steel prong (as opposed to stretching the neoprene itself). If length shortening is required, simply cut the neoprene with scissors. Please note that unlike rubber, neoprene does not perish with perfume and the body’s natural oils.
