With all the pen paraphanelia that I carry around I need something to transport it. I have several bags but right now I am using my Maxpedition Falcon II backpack as my EDC bag. It is the one on the right. The similar looking pack on the left is a Condor look-a-like that I no longer have. I don't have a current picture of the contents but I have my Lihit Lab Teffa bag in it (with Rhodia #16 Dotpad and some work documents. My self made fountain pen test notebook, work notebook, 12 pen leather case, extra phone battery and cables, IEM's, and a Uniball Alpha Gel ballpoint. You never know when I will need it for filling in triplicate forms. I also carry around some snacks and a small toolkit.
