An 11-piece set of long flat wooden boards, made to perfectly complement our large rainbow stacker.
By sandwiching rainbow stacker pieces side by side with stacking boards, you can create a whole world of new tiered structures. Stack them up high to construct a storied skyscraper. Position them vertically to create a fence or barrier fantasy land. Or lay them out flat on the floor to create countless colorful patterns and figures. Bridge the gaps and valleys of your wood block city so that other toys can trek to the other side.
Kids, parents and teachers agree. Combining rainbow stacking boards with the original stackers will multiply your playtime possibilities by infinity.
