How many do you need? I have a few. I'll try to figure how many i want to keep. Any preference, Kodak or Kentmere? The Kodak are much more heavy duty.
I didn't check whether the Kodak were film or paper boxes come to think of it. I got a surprise reaction one day when I took prints in to U Akron for critique. I used a 16x20 Kodak film box. One of the teachers who shoots 4x5
said, "Wow, that is really intimidating."
I would gladly take whatever you're willing to part with, film or paper boxes.
