It is hard to tell from the picture and even sitting on my shelf that these are completely made of cloth because of the great texture. These were inexpensive and the quality reflects that - some loose threads, handles a bit askew, etc.  They would be great for light items, but are a little flimsy for my intended purpose which was to put the game console remotes and discs in.  Another reviewer said they worked great on their shelf.....these are completely square so they hang over the edge on a standard book shelf.
