GTD Folders, paper style

I have read the book Getting Things Done. The Art of Stress-Free Productivity by David Allen and I have been trying to get my hands on some of his recommended folders to do all my paperwork. It has been really hard to find them in Europe (at least Germany and Austria). Finally I found comparable Folders on Amazon.

Leitz: Leitz Einstellmap.m.Tabs cham. 2434VE100

These ones are exactly like the normal US manila file folders with easy to label latches. I can really recommend them.
