Features Special Needs Development Wooden Material No batteries Battery Non Rechargeable Width x Height: 114 mm x 102 mm Description Whack the ball and watch it disappear! Children will love pounding the ball and watching it roll down and around, from top to bottom – again and again, with the Wooden Hammer Ball Game. This game is an exciting and interesting game, great for helping toddlers develop a solid sense of hand-eye co-ordination: Firstly, by hitting the balls through the holes with the wooden hammer, then by following the ball with their eyes as it travels on its journey to the bottom. Young children will be taken in by the Pound N Roll game’s regularly shaped platforms painted in vibrant primary colours, and parents will appreciate the game’s timeless wooden charm. We've taken the classic pounding toy to new heights! Knock the four brightly coloured balls through the holes, then watch and listen as they roll down the ramps. Sturdy wooden hammer included. Package includes: 1 x Wooden Hammering Toy Set (include 1 wooden shelf, 4 ball, 1 hammer) Thank You!!! Customer Service Video
