The Grimm’s 12-Piece Rainbow is a beautiful invitation to open-ended, imaginative play. Crafted from sustainably sourced lime wood and glazed with vibrant, non-toxic water-based colours, this iconic wooden rainbow encourages children to explore, create, and discover in their own way. With twelve curved arches, it becomes whatever a child needs in the moment: a bridge, a tunnel, a mountain, or a magical landscape limited only by imagination. Rooted in the philosophy of Waldorf education, Grimm’s designs prioritise sensory exploration, creativity, and independent thinking. Each piece communicates the brand’s credo: Joy through colour! The rainbow’s tactile surfaces invite repeated handling, allowing children to experiment freely and return to the toy at every stage of development. Open-Ended Play for All Ages For younger children, the rainbow offers endless opportunities for stacking, nesting, balancing, and sorting. Little hands naturally explore size, sequence, and symmetry while building towers or lining the arches from smallest to largest. These activities develop fine motor skills, hand-eye coordination, and spatial awareness through joyful, hands-on play. As children grow, the rainbow transforms effortlessly. The arches can become bridges for toy cars, tunnels for trains, fences for farm animals, cradles for dolls, or rolling hills for imaginative landscapes. Turned on their sides, they become boats on imaginary seas; stood upright, they inspire sculptural creations and inventive architecture. Its versatility ensures that the toy grows alongside your child, adapting to storytelling, small-world adventures, and inventive construction play. Unique, Handcrafted Design Each rainbow is hand-sawn from a single slice of lime wood, creating subtle asymmetry that gives the toy its natural, organic charm. Individual arches may need slight rotation to fit perfectly—a feature that highlights the craftsmanship behind every piece. Colour and size variations, visible grain, and natural knots are all normal characteristics, making each rainbow unique. The water-based stain ensures a beautiful, tactile finish that encourages exploration while remaining child-safe. Dimensions & Materials: 12 pieces Length: 35.5–36.5 cm | Height: 17–18 cm Lime wood, glazed with non-toxic water-based colour Tips for Thoughtful Play To encourage free, creative play, it’s recommended to place the arches in a basket rather than assembled. This way, children see the pieces as versatile building materials rather than a fixed rainbow shape. This approach nurtures imagination, allowing endless combinations and fostering problem-solving skills. The large rainbow is a real all-rounder. It looks beautiful on display, but its full potential comes alive when children explore it individually. It supports a wide variety of play experiences: stacking, building fantasy landscapes, creating small worlds, sorting colours, designing simple or complex ball tracks, and even energetic movement play. Recommended for children aged 3+, though approved for 0+, the Grimm’s rainbow has been celebrated by the Spielgut (Good Toy) guide for its educational and creative value. With its seven traditional rainbow colours—red, orange, yellow, green, light blue, indigo, violet—and additional shades like ruby red, light green, turquoise, purple, and dark red, it is a vibrant tool for joyful, mindful play. For parents and caregivers in the UK who value sustainable, thoughtful toys, the Grimm’s 12-Piece Rainbow offers years of meaningful play, inspiring creativity, imagination, and learning through colour and open-ended discovery. Marble Runs and STEM Play The Grimm’s 12-Piece Rainbow pairs beautifully with Grimm’s wooden balls, making it a favourite for marble runs and experimental play. Children can position the arches on their sides to create tracks, tunnels, or chutes, designing unique paths for the balls to roll through. Turned upside down, the arches produce a gentle, melodic sound as the balls run down the centre, adding a sensory dimension to play. Marble runs with the rainbow encourage problem-solving, perseverance, and critical thinking. Children experiment with angles, spacing, and balance to create a successful track, developing STEM skills in physics and engineering concepts along the way. As they test, adjust, and try again, they learn resilience, cause-and-effect reasoning, and the joy of hands-on discovery. This playful combination turns the rainbow into a dynamic learning tool while keeping imaginative, open-ended play at the heart of every experience. About Grimm's Grimm's toys are inspired by the principles of Waldorf Steiner and are designed with the intention of helping children discover and develop their own creativity through simplicity of shapes, leaving plenty of room for independent play and imagination. Inspired by the educational philosophies of Rudolf Steiner, Grimm's puzzles, building sets, and toys are about the rainbow, happy colors, creativity, and the imagination. There are no instructions, and you can do no wrong with a Grimm's toy. Just play, learn, and enjoy. Find out more in our Grimm’s Toy Guide. Please note: as Grimm's uses non-lacquered wood, some paint transfer can occur during play. This is considered normal. Non-lacquered wood has a lovely texture - the rough texture of the stained wood is not only an important tactile sensory experience for children, but those rough surfaces makes it possible to build in many different ways, because the parts do not slide down so easily as the wood surface is still natural and not covered with a layer of bright enamel; however if you are concerned about paint transfer we suggest you purchase another item that is lacquered to be on the safe side. Product number: 10670 Materials: lime wood, non-toxic water based colour stain.
