We used to distribute them. They erase permanent ink.

Curious. What are you all writing on your film and why?

HABS/HAER requires a project and negative number to be written on the base side of the film along the top edge in the rebate next to where the code notches are.

Isn't that kind of the point of permanent inks - to be non-removable? Probably want to check at least twice if not thrice before committing anything to writing with one of those...

Or did I miss something?
