Great for knick-knacks and toiletry items

Perfect for the bathroom. I love that you can position the shelves in different arrangements. Sturdy enough for knick-knacks and toiletry items. Looks exactly as pictured.

Decent
Color: Dark Brown, Size: 15.7", Color: Dark Brown, Size: 15.7"
Instructions aren’t very clear. Takes a bit to figure out. Pretty cheap quality, but seems to be sturdy. The metal basket part of ours came rather bent and had to do some bending to get it to fit right. Decent size could be little thicker. They look good though once up.
