It's currently trendy for desks to no longer have drawers, creating a market for desktop objects that can store odds and ends. Japanese stationery company Nakabayashi thus makes these Lifestyle File organizers out of sturdy paperboard.
Sized like binders in A4 and B5 sizes, they're essentially little desktop lockers.

They also make this File Box M version that can live on your desktop without taking up the space of a binder:
Nakabayashi only takes wholesale orders on their website, and at press time I couldn't find a U.S. distributor. The wholesale prices are $35 for (12) B5 units; $40 for (12) A4 units; $30 for (12) File Box M units; and $20 for (12) File Pen Stand units. I think that leaves room for a pretty good markup.
