Hi, found some old negs, just wondering why they are purple. I would think they are C41, don't think they did b/w at all ....

Also the side lock sleeves, they cannot be stored in ringbinders right and does one need like 6 strips of them for 1 roll of film? The pictures seems to show a strip at a time, also are they separated so you have 6x separate strips per roll?
