I used these to put a backing on a cube shelf we bought secondhand that they neglected to put the original backing on and they worked like a charm! They were a bit larger than the cubes themselves so I had to cut some down which I did with great difficulty with a box cutter. They’re very thick, very sturdy, and totally worth the price. You probably want a better tool or method than I had to cut them down but for my use it’s fine since it’s the back of the shelf!

It’s smaller than expected, make sure to check measurements

Good quality
