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: Image here: https://i.imgur.com/pVfkFqW.jpg At this point, these seem to be the low-price leader at $5.73 each. --Chuck
