Classroom Organization: Papers to Hand Back

I have been working with these IKEA Flyt boxes for years.  They are $2 or $3 for a five pack, and they will stand up to several years of use before they need to be replaced.  If you are willing to reinforce them with clear packing tape it could last even longer.  I tend to just replace them, because they are cheap and I am always looking for a reason to head back to IKEA.

I am using these for all those papers that are graded and waiting to be handed back.  I bought scrapbook paper from Michael's and used my silhouette to cut out the numbers for the periods (5th is my conference period).   Then I used Modge Podge under the paper then over the paper.  I may end up giving it a few more coats so it can stand up to high school kids.  

How do you organize graded papers?  Did you see Chonte's Math Classroom post?  Did you see her paper organizer?  Are you jealous?  She has the best finds.
