The only thing one can do with canisters these days, once the film is removed, is glue them on a magnet und attach to the fridge door. Serious, No. 1 is not a real option, I used No. 2 in case of an emergency, but cut the edges of both films, similar cut to loading on reels. No.3 they can be reused 3 to 5 times - I was told, after second use I tape them to avoid popping open.(posted 8718 days ago)So there is almost nothing like some good old Ilford ones I received from a friend (Thanks Jochen!). Still reloadables are Maco and Fomapan, I do not know about Efke, because I was never able to get a single film only bulk film.
