Green Walnut's wooden rainbow stacker surrounds children with bold, beautiful colour while inviting the open-ended play that fuels imagination and creativity. This Montessori-inspired, multi-purpose set of wooden arches captivates toddlers, kids — and even adults — for hours at a time. The bundle gathers 12 pieces of the Large Wooden Rainbow, 11 large semi-circle plates and 12 large peg dolls, all made of premium pinewood. The large rainbow measures L 35 cm x W 6 cm x H 16 cm, the semi-circle plates L 37 cm x W 18.5 cm and the peg dolls H 6.5 cm x W 4 cm. There is no right or wrong way to play with a rainbow stacker — which is exactly what makes it such a unique open-ended toy for very young children and older ones alike. Used together or individually, the pieces become bridges, tunnels, seesaws, fences, houses, doll cradles or caves. Along the way, the toy stimulates reasoning, spatial awareness and problem-solving, refines eye-hand coordination and motor skills, boosts critical thinking and deep play, builds nesting and stacking ability, and helps children learn their colours. A few things to know: the stacker is deliberately not polished perfectly smooth, since a little friction is needed for the arches to stack. The non-toxic, water-based paint is less uniform than other paints, and screen display may create slight colour differences.
