Grimms Large Natural Rainbow Tunnel

GRIMMS

A set of twelve natural wooden arches that nest together and stack apart into a large tunnel, bridge, fence or little house. Open-ended pieces like these become whatever a child imagines, from marble runs to small-world scenes, and pair with other building toys. Encourages creative, open-ended play, early engineering and fine motor skills. Finished in lime with non-toxic water-based dyes.
