I use a simple, not particularly beautiful one that Staples sells. It's their Item 806950 (Model 10604-CC):
Staples Rotating Organizer, 8"H x 7 1/2"D, 11 Compartments
Here's a picture (don't know if this will work):
It's inexpensive, functional, and takes up very little space. Mine holds sticky notes, correcting pens, pens, highlighters, scissors, letter opener, staple remover, rubber bands, and paper clips. In fact, I carry one to sell to clients when I'm consulting - very handy.
FYI I've listed this and other basic processing supplies on my Amazon "listmania" list: Basic Processing Tools for Personal Productivity/Workflow.
