Make a million and 1 play setups - Are you in love with the classic rainbow stacking toy? 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.
