Happy Rainbow 彩虹製造機

The refracted light from this decal turns my entire kitchen counter into a swirling disco of rainbows on sunny afternoons—even better than the prism I used to use. Placement was a breeze; just peeled and stuck it on the window, and within seconds the rainbows started dancing.

My cat sat in a sunbeam this afternoon and the rainbows scattered across the wall made her go cross-eyed trying to catch them. The vinyl itself is thin but sturdy, and it stuck perfectly to the glass without any bubbles.

Stuck it on the kitchen window this morning, and by noon there were rainbow spots dancing across the counter—the vinyl really does refract light that cleanly. It took me all of thirty seconds to smooth it on, and it hasn’t budged since.
