Pick up this great gift idea. Made with micron-sized iron-based particles distributed throughout the astonishing moldable magnetic putty takes on the properties of a magnet itself when placed in close contact with the included Neodymium Iron Boron magnet. Essential Details: Ages 8+ Made from reclaimed steel tin magnet silicone rubber Measurements Tin container: 4" dia. x 1" H; Magnet: 0.5" cube; Putty: 3.2 oz. Notes: Please note: At first the putty is not magnetically charged. To activate use the included magnet to align the putty's magnetic forces. Hold the magnet to the putty for 5 seconds. Once it's charged watch your putty be attracted to or be repelled from the magnet! Made with silicone-based inert non-toxic synthetic rubber; contains no latex/wheat compounds.
