Kartell's Optic storage cube is visual eye candy. Yes, they are bright lollipop colors, that is a given. The fun fact about the faceted cubes are that they are made in PMMA Optic and the surface is decorated transparent and/or mirrored pyramids that create a really unique re_ected visual effect. The cubes can be stacked or lined up next to one another...whatever combination you can imagine. Optic comes in two versions: closed with a door or open without door.
