The lid actually snaps shut instead of just resting there, which is what I wanted for keeping loose receipts and school papers from spilling. Holds a full ream of 8.5x11 without bowing out at the sides too. Grabbed a third one for the garage shelf.
Bought two of these to wrangle the paper clutter on my desk, and the 6 QT size fits a full stack of 8.5x11 sheets perfectly with room to spare. The lid snaps on tight enough that I can stack them without anything shifting around.
I was a little skeptical about the lid staying on, but it snaps shut securely and the 6 QT size is perfect for sliding under my desk. It's been holding all my 8.5 x 11 paperwork without bending a single corner.
