Use these for storage above cabinets. 

I like that they have a semi-rigid bottom and sides. It’s somewhere between cardboard and poster board so they hold their shape fairly well. 
I wouldn’t try to put anything heavy in them and carry them but for storage they are perfect and keep dust out. 

I was looking for something that could hold long items including rolling pins, wine making supplies and roasting pans. These are perfect. Very pleased with the purchase; just check the dimensions. These are fairly large.
