These collapsible bags are so versatile! Here are a few ideas of what to use them for…

I bought a bunch of these bags to pack my son’s things in for college move-in. I liked that they hold a LOT of stuff, have convenient handles for carrying it up flights of stairs, and that once we unpacked them, they would collapse so as to not take up a ton of space in a small dorm room as we were unpacking.

I bought this to store blankets under the sleeper sofa in my camper, and it worked great. The blanket will stay clean, and because the bag is flexible, it fit under the sofa without any problem.

I used it to put all my Christmas decorations in; it perfectly fit a 6ft tree with all decorations. It suited me because a bin is too heavy to place up high in a closet.
