This is a perfect way to store and organize small things because you can store it on a book shelf neatly. Also, it is nice when you have to take documents back and forth - it is sturdy and you don't have to worry about pens or discs falling out if you tip the file over. It is also great for craft projects.
I have been using these cases to organize my cross stitch projects, and I don't know what I would do without them. They keep everything together, so all I have to do is grab the case. They are wonderful for travel, when I stitch directly out of the case.
I do sometimes think they could be higher, because when they are stuffed full, they bulge and the top and bottom don't fit completely together.
I use this case to store numerous ink spots I have from Stampin Up (stampers will know what I'm talking about). It is the perfect size and is transportable as well as stored in an organized fashion. I love it!
