These are very very sturdy, which is why I had such a hard time with them... I ordered 2 and wish I hadn't (yet more money wasted, buy something I don't need)... I at the time don't have a ton of paper, and had a very very very hard time getting these in the form / shape they should be.. I ended up going with a horizontal storage system instead..But I can totally see why folks would like them.. Perhaps as my scrapbooking stuff grows, I'll be able to use these :)
