Apluses Clear Rainbow Cubes

Hold one up to the light and the whole cube turns into stained glass. The transparent Apluses sets use the same one-inch format as the solid ones, but the shell lets children see the magnet inside sliding to meet its neighbor.

They are a favorite for light tables, windowsill towers and color-mixing games, and they click into any other Apluses build.
