I ordered 5 sets of these to help organize our home papers and kids school papers. The dimensions are perfect for use on our bookcase. My main complaint is that the shelves aren't attached to each other. They simply stack on top of each other. This is a problem for my kids because they can be rough with them and knock them askew easily. As long as your careful when pulling items in and out, it's fine. I have mine wedged in with other baskets so that helps keep them from completely falling down if the kids accidentally bang them. Great price and I like the minimalist look and black color!
