Wall Coaster Extreme Stunt Set
5 years & up. The Extreme Stunt Set is simply amazing! It comes with many of the pieces of the Super Starter Set, plus, various trick parts that let you make the marble fly through the air, loop-de-loop, zig zag and twist in ways that you can only imagine!. Each part is made of lightweight ABS plastic and sticks to the wall with re-usable fun tack (the same material that sticks posters to walls). This allows the Wall Coaster to be used on almost any surface and the design can be changed many times by simply repositioning the parts with the same fun tack.
