Sticky Stones are small smooth pieces of iron ore that have been powerfully magnetized so that they stick together in in clumps. Your child will be amazed by building structures and creating little stone sculptures. The magnetic quality of these natural stones will draw you into the play as well. Place one stone in the palm of your hand and place your hand under a table. Watch as the remaining stones dance and jiggle on top of the table! This pack contains approximately 15 ounces of Sticky Stones, enough to fill the included 3" x 4" pouch. Also included is an activity card that tells about five fun activities that you can do with your Sticky Stones. Meets Federal, and ASTM 963-07 Toy Safety Standards. Recommended for ages 5 and up. Stones have powerful magnetic force and vary in size, so this item is only appropriate for a child who no longer explores toys with his mouth.
