Stacking and tinkering! This large wooden stacking tower in rainbow colours makes an impression with an additional task: the differently sized wooden discs must not only be pushed onto the pole in the correct order, but also turned to the right position so that the gaps in the discs match up with the position of the small pins on the pole. It's a tricky task that trains fine motor skills and problem-solving skills! The rounded base allows the completed stacking tower to wobble around as a fun reward.
