We have been buying this apple juice which comes in pouches, 10 to a box. The boxes are just too good to throw out! They are a double walled box, with a thickness of a little over 1/4 inch. They just perfectly fit a CD box cross-wise. So far I have made a box to hold Christmas cards and 3 boxes for photo CDs, which also fit perfectly on the shelf. As you can see, I labeled the card one on the side and the CD ones on the end.
