Are you looking for an amazing wall activity for your pediatric office waiting room? The Rainbow Wall Dominos would be just the fit. The design of these wooden wall elements makes them appealing and adds a rainbow of colors to any room. There is always something to push, turn, pull ... and to observe. Chain Reaction: When the child bumps the first block, the others fall down one after the other. The blocks stand back up when the ball is pulled underneath. Helps with hand-eye coordination and fine motor skills. Made of birch wood veneer with child friendly stain and clear lacquered finish.
