Super Metallic Magnet Stones by the pound! Darkly Iridescent and Polished until they are super shiny, these 6 pieces of magnet stones weigh approximately one pound. They make a great desk top toy…but you should keep them away from electronics as their magnetic field can cause harm to sensitive equipment. Use them for experiments with magnetism. Due to Natural Variation in Metallic Super Stones no two are identical. Pictured is a representative of selection. Ages 6 and up.
