Grimm's products are always unique with unique traces of nature left behind. With a few exceptions, everything is sanded and sawn by hand - this gives a different expression than pure "machinery-work" and ensures the uniqueness of each piece.
They use alder, lime, beech and maple wood.
All rainbow friends and decorative figures are hand-painted and decorated in the most loving detail. In assembly and packaging, Grimm's works in part with workshops for adults with special needs in Germany.
