We love wood because it is a natural material so it always has various markings that show up in Grimm's products, making each one unique. Grimm’s toys are always one of a kind, carrying unique marks made by nature. Wood grain has changing structures and colours which serve as proof of its natural origins. The unique variations are proof of quality, not defects. Discover the markings that make your Grimm’s toy Simply Unique! Wonderfully tactile and versatile construction pieces.
