Moving my old tax returns out of cardboard boxes was long overdue, and these fit both my letter and legal hanging folders without any wobble. I stacked all four in the garage and the plastic feels thick enough to survive a few basement floods.
The snap-tight lids actually stay put, which was my main worry after my last set kept popping open. I've got both letter and legal folders in these and they fit without any forcing. Four boxes cleared out an entire closet shelf.
These boxes finally got my overflowing home office under control, and I love that the same sturdy plastic container works for both my letter-size papers and legal folders. The snap-tight lid really does keep everything dust-free and secure, even when I stack them two high.
