I use the fine tip Sharpie brand pens as well. I bought a pack of several and put a couple in each bag. Never had them fade on me and they won't smear as long as you give them a short drying time.

Everything gets marked N, N+, N- and so on, location(s) and date(s), as much info as I have room. Obviously there is more label real estate on 120 film.
