These are essentially larger versions of the zippered plastic packaging that comes with new curtains, pillowcases, and linens, and feel overpriced for what they are. There is absolutely no structure to them, which is actually an advantage if you're planning on using them for storage under beds with limited clearance between the bed and the floor as they can compress and fit into narrow spaces - but won't work at all if you're planning on, say, stacking them neatly in a closet or attic. And the handles and zippers seem reasonably sturdy, though of course only time will tell how they hold up.

Not as sturdy as I would like but has a lot of space in one bag!! Easy too slide from under bed if not too packed
