Office supplies desk caddies

If your desk is anything like mine, there are pens, pencils and markers all over it, and while this means they are within easy reach, it also means that they take up valuable desk space. What I really should have is a desk organizer in which I can put all my writing implements, plus paperclips, erasers and post-it notes.
