Poorly described ... there are screws that go through the outer wall of the shelf to hold the shelves in place ... this looks very tacky. You cover the screw with a vinyl sticker to make it even tackier. The screws don't set in level, so the sticker bubbles over the screw and isn't a bit discreet. And when you nail the back boards on, the thinness of the boards means that the nails will push out the particle board slightly, causing slight bulges along the way. I was definitely expecting something engineered more tastefully. Also, the ad said the shelves could hold 22 pounds, but the instructions say 10 pounds - that is a big discrepancy. Not sure which is correct, but the thin particle board would lead me to believe it's only 10 pounds. Also, I did not realize that the way described the white finish would mean glossy white. They don't work at all in the space I need, so I will find a use for them elsewhere.
