Where can I find a traditional Japanese desk?

I am looking for a tray that I can store paper in that can hang off a desk, where can I find one?

• I have checked office supply stores and places like that, so I am wondering if anyone knows any places online that would have something like this? The type of thing I am looking for, is where there is a hook of some sort that extends from the tray, and rests against the side of the desk, and then paper can be stored in the tray. Thanks in advance

• Answer:

  I've bought trays like that several times in places like Staples and Office Depot. Go back and look again.
