Grimms rainbows
Grimm's iconic Large Rainbow has now been joined by other members of the family. The Large Pastel and Natural Tunnels also have twelve pieces, but watch out for the 10-piece Sunset Rainbow and the half-size and mini equivalents.
These pieces are cut by hand from a single piece of wood. They are often slightly imperfect in shape and may only fit together in one direction. This is perfectly normal and doesn't affect how they are used.
