A classic stacking toy, there are endless possibilities for configuring Grimm's Neon Rainbows. Responsibly made by a family-owned company in Germany from wood sourced from sustainably managed European forests, Grimm's Rainbows are toys that are meant to last a lifetime. They are as beautiful as they are fun to play with. Each 10-piece set is finished with non-toxic water based stains and is safe for young children ages three and up.
