Just got Larry Urbanski's film cans in--about the same as the others;
800' can fits a 10.5" tape reel perfectly. The difference is that
Urbanski's aren't vented, which, while being a minus for acetate movie
film, is probably a plus for mag tape:

At this point, these seem to be the low-price leader at $5.73 each.
