A rainbow for stacking and inserting! This stacking tower shines with bright rainbow colours and the wood material that's easy to hold encourages even the youngest children to sort the differently coloured rings according to their size and colour. This promotes the development of motor skills, hand-eye coordination, and understanding of shapes and sizes. The rounded base that lets the stacking tower sway back and forth provides extra joy. Child-friendly stacking games made of robust wood guarantee long-lasting playtime fun. The young ones won't be bored anytime soon!
