Grimm's | Stacking Puzzle - FireThe Grimm's Stacking Fire is very versatile and ideal already for small children. Toddlers stack, sort and build and as the children get older they will use it as fence for animals, a tunnel for vehicles, a house for dwarfs or dolls or just to build amazing sculptures. Grimm's Stacking Fire is a great toy for imagination and open ended play. Grimm's Stacking Fire is made from precious lime wood and finished with a non toxic water based colour stain.
