Wooden Rainbow Stacker – Nesting Arch Building Blocks
A Little Wooden Rainbow with Plenty of Ways to Play
Build a bridge, arrange a curving path or nest the pieces into a rainbow again. These wooden arch blocks turn a simple shape into an open-ended building set, with five color palettes to suit bright play spaces and softer, nature-inspired corners.

Curved Wooden Pieces for Stacking and Nesting
- Graduated arch shapes that nest together into a rainbow.
- Separate the pieces for bridges, tunnels and simple building arrangements.
- Wooden construction with colored surfaces.
- Five palette options, from Classic Rainbow to muted blue and earthy tones.
- Compact form for tabletop or floor-based play.
For Little Building Scenes and Shared Playtime
Arrange an arch over a make-believe road, create a small landscape or take turns trying a new stack. The same curved pieces can become part of different scenes, without needing one fixed finished design.
Why Choose Blocks That Become a Rainbow Again?
Picture a tiny bridge leading into an imaginary town. After the story ends, bring the arches back together and the whole scene becomes a rainbow once more. The nested design gives the pieces a simple, recognizable arrangement between building adventures.
