What a fun game the Grimms Small Wooden Stacking Game Natural Rollers is! Kids will have endless hours of fun slotting the different sized cylinder rollers in the holes in the sorting board. They can be used to stack up and build towers as well as piece the puzzle together so there are no gaps on the board! Children will enjoy counting games and rolling them across the floor in some of the various ways they can be played with. This educational wooden building block set would go very well with other items in the Grimms range which you can view here. Due to the unvarnished surface, these blocks stack really easily and don't slip around!
