Material 100% hypoallergenic stainless steel, black neoprene rubber size drawing – 80 x 60mm (3.14 x 2.36 inch), necklace – approx. 220 x 110mm (8.66 x 4.33inch) stainless steel whimsical ‘hand drawn’ necklace with a continuous line that extends seamlessly from the ‘drawing’ 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, 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. Please note that unlike rubber, neoprene does not perish with perfume and the body’s natural oils.
