<p>I just use short strong nail scissors to cut the round ends of a 120 spool to a smaller diameter. It is plastic these days. Why do you others not do that? There must be a downside or everyone would be doing what I do? The length of the spool has not been as issue, so just clipping the disc ends to make them smaller has made using 120 film easy and so I have not needed to collect 620 spools etc.</p>
