Acryl-regenboog-eenheidsblokken - Set van 16

The colored acrylic panels catch the sunlight so vividly that my daughter turned our living room window into a rainbow castle, and the blocks stack perfectly level thanks to their precise edges. It’s a solid set that makes light play genuinely engaging for open-ended building.

My toddler loves holding these blocks up to the window to watch the colors project onto the floor. The acrylic pieces feel smooth and sturdy, and the rainbow set is perfect for teaching color mixing while building.

I was surprised how much the colored blocks catch the light when stacking them near a window. The variety of shapes in the 16-piece set is decent, though I wish there were a few more basic rectangles for symmetry. My toddler loves holding them up to see the colors change.
