If your child needs and fun and educational activity, the Wall Coaster Super Starter Kit is the perfect solution. Each kit contains the necessary components to build a fun marble run course- right on the wall! Invented by a 12-year-old boy, this action-packed kit is sure to provide hours of entertainment. This innovative set develops strategy, hand-eye coordination and spacial reasoning. It uses the basic laws of physics and gravity for hours of fun and excitement. The specially-designed coaster tack is created to adhere to most wall surfaces without leaving a mark. Best of all, the reusable tack allows you to change and re-design the paths whenever you want! However, this kit should not be used on carpet or other porous surfaces, nor should it be used on wallpaper or newly-painted areas. It is recommended to test a section of track before setting up the entire kit. Each set includes ten 4" coaster tracks, ten 10" coaster tracks, three 6" coaster tracks, four coaster bands, four blue lightweight crystal marbles, four glow-in-the-dark crystal marbles and one package of reusable non-marking coaster tack. This item is recommended for ages 5 and up. PAYMENT POLICY We Accept Most Payment options including Credit cards, Debit cards, and Credit/Debit gift cards; PayPal and PayPal Credit.
