Bring colour and creativity together with Grimm’s Rainbow Mosaic Block Set, a charming collection of 36 wooden cubes in vibrant rainbow shades. Each 4×4 cm block is crafted from smooth, high-quality lime wood and presented in a sturdy wooden frame, perfect for both play and display. The tactile, solid cubes encourage hands-on exploration and inspire children to build, stack, and experiment freely.

With these colourful blocks, children can construct everything from playful towers, houses, and castles to sprawling miniature cities and landscapes. The versatile shapes also make them ideal for pattern-making, counting, sorting by colour, and early maths activities. Open-ended play encourages problem-solving, spatial reasoning, and fine motor development, while fostering imagination and independent thinking.

Designed to integrate seamlessly with all Grimm’s 4×4 scale sets, including the Large 1001 Nights, Romanesque, and Colours & Shapes collections, this set offers limitless opportunities for expanded creations. Finished with non-toxic, water-based stains and plant oils, the Rainbow Mosaic Blocks are safe, eco-friendly, and built to last, meeting  European toy safety standards. Compact yet bursting with creative potential, this set transforms simple wooden cubes into a vibrant playground for children’s ideas, helping them learn, explore, and play in truly colourful ways.

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.

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.

Made from - Sustainable Harvested Wood. Lime wood, non-toxic water based colour stain, non-toxic plant based oil .
