Make a million and 1 play setups - Are you in love with the classic ? Add in an extra layer of fun (and learning!) with these building boards! The set of 11 slats match up end-to-end with our rainbow stacking arches - so you can use them as bases, steps, ramps, and more! The only limit? Imagination!

Open-ended play, the rainbow way- Love the rainbow, monochrome, or pastel look? Our unfinished wooden toy is easy to color with acrylic paint, wood stain, natural dyes, chalk paint, or liquid watercolor paint.

High-quality & DIY educational toys - Made of premium Baltic birch plywood, and always pre-sanded, our rainbow building boards are ready for hard play - as soon as you take them out of the bag! The planks are 2-¾ inches wide. The largest one is 14-1/4” long, and the smallest is 4 inches.
