These fabric storage boxes really took me by surprise. I thought that they would be flimsy and not hold much weight. These boxes are extremely well built and hold a lot of weight. I put all my 35 bottles of acrylic paints, and my canvases, my full roll of paper towels, a bunch of rags  my plastic bag for garbage and then a bunch of plastic cups for pour painting in just one storage box. And I have a little space leftover. I highly recommend these storage boxes.
