Foam GeoShapes™ possess large interior diameters which make moving through them easy and fun. Wood or hard plastic models can fall on children and cause injuries…not so with Foam GeoShapes™. They’re 2″ square and constructed of semi-firm durable cross-linked polyethylene. Each shape includes a 2 lbs. solid rubber base which provides stability even on windy days. Use them as move-through obstacles or throw-through targets. Includes six primary shapes in 6 COLORZ; square, rectangle, circle, triangle, oval, and diamond.
