彩虹積木 - 閃光水

The acrylic windows are thick and really do shimmer when the light hits them, way nicer than I expected. My daughter holds one up to the window and watches the water wobble for ages. They're the same standard size as our other blocks so everything fits together properly.

My kids stack these right alongside their plain wooden blocks since they match the standard unit size perfectly. The acrylic windows are sturdy and the water inside catches the light beautifully on a sunny windowsill.

The water inside actually moves when my kids tip the blocks, which keeps them mesmerized way longer than our plain wooden ones. They're sized to match our standard unit blocks, so they slot right into the tower without wobbling.
