Enjoy the quiet and meditative rolling motion as you "roll the dice" between your fingers. The five highly polished stainless steel cubes looks great with your power suit or your boyfriend tee. If you need more of a chunky, tactile experience, slide the cubes along the necklace and add some hum to your day. The ball chain necklace is made of stainless steel and is 30" long and the balls are 2.3 mm.
