Acrylic Rainbow Unit Blocks - Foundation Set

My kids have been building towers with these for hours and the acrylic pieces catch the light so nicely on the windowsill. They fit perfectly alongside our old wooden blocks too, which I didn't expect.

The colors look amazing when sunlight hits them through the window. My daughter spent an hour making a "stained glass castle" and the blocks fit together perfectly with her wooden set.

My kids build towers with these every morning and the light shining through the colored acrylic is honestly beautiful. They're sturdy enough that my four-year-old hasn't chipped a single one yet.
