Fits a full year of client invoices with room to spare, and the lid doubles as a little tray for paperclips while I'm sorting. The plastic feels thick enough that I don't worry about the corners cracking when I stack two of them.
I’ve been through three different file boxes in the past year and this one finally feels sturdy enough to actually stack under my desk without bowing. The lid clips on tight when I carry it to meetings, and the black finish hides scuffs way better than the clear plastic ones I had before.
The wing-lid snaps shut so securely that I don't worry about papers sliding out when I carry it across the office, and it's sturdy enough to stack a couple of other boxes on top. Fits letter-sized files perfectly, and the organizer slots in the lid are handy for pens and sticky notes.
