This is a toy that is used again and again - it's used as tunnels for train tracks, for running cars etc under, it's stacked and used to make wonderful and beautiful contraptions with the treeblocks, we also have.
There is actually a larger version for gardens too.
Because I am waldorf influenced, all the toys for my son are wooden, and Grimm's produce some seriously beautiful pieces. Also as a childminder these toys are sturdy and wood is naturally anti bacterial. And as an adult I don't mind having these toys on display as they are so lovely and no one can resist touching and having a play. Wood is just so tactile, and the rainbow vibrant, but not glossy, colours are wonderfully appealling.
