*Grimm’s love wood because it is a natural material so it always has various markings that show up in our 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.
