I use these boxes to pack when I move classrooms. You can get a lot in them and they aren't too heavy. I've also used them when I moved homes. They hold up really well.
These boxes serve as temporary storage for many items. I use them to get books off to the friends of the library to store old records to sort items for different purposes like clothing photos etc.
I needed inexpensive storage for my many pieces of fabric. These boxes fit on an existing shelving unit 2 across and then I put an attractive scrapbook colored & patterned paper across the front with the fabric colors labeled. Storage for a fraction of what wicker baskets would have cost and there is a lid for protection.
