Kids will spend hours building castles and fortresses with these sturdy cardboard blocks. This castle set includes 32 pieces: 6 large red, 6 medium yellow, 6 small blue, 6 turrets, 4 arches, and 4 doors. Red blocks measures 12"" x 6"" x 3"" and are made of corrugated cardboard covered with a water-resistant coating. Bricks are light enough for a toddler, but strong enough to hold 200 pounds. No one can get hurt when they fall.Ages 2 to 6By Smart Monkey Toys
