The Tooky Toy Wooden Rainbow Stacker is a vibrant, multi-functional set designed to playfully stimulate a child's imagination and fine motor skills through endless building possibilities. Whether stacking the arches, creating unique shapes, or using them as tunnels and bridges for other toys, children are encouraged to invent and explore at their own pace. Aligned with Montessori principles, this open-ended toy promotes self-directed learning and problem-solving without the constraint of fixed rules. Each piece is crafted from a combination of pine and plywood, and finished with beautiful muted colours. Suitable for children 18 months+
