Design & Drill Activity Center powers up their imaginations and builds coordination and creative thinking skills as they drill chunky, child-sized components into a sturdy activity board. Children love following the colorful activity cards to create pictures and patterns - from trains and boats to flowers and fish. Young builders can drill their very own designs. Simply snap any one of the drill bits into the power drill or the screwdriver handle, grab a handful of bolts and turn on the learning fun. Pieces include chunky plastic bolts, a reversible power drill, a screwdriver, three drill bits and a combination wrench for tiny hands. It requires three AA batteries (sold separately). Built child-tough, this durable center is recommended for children ages 3 to 6.
