I use these to put matching paper, stickers, die cuts, etc. in. It is much easier when they are all together in one place. They fit perfect in the Cropper Hopper paper holder.
The Paper Files, along with the Paper Holder and Dividers have helped me get all of my papers completely organized. I'm very happy with the paper files.
I keep all of my scraps in these folders now in the easy access paper holder next to the paper line it's from.
