These were also cut down from 70mm stock and have small sprocket holes along one edge. Minimum order is 3 rolls. The paper leader and trailers are the identical length of standard 220 film so loading the films is identicle. Unlike the 35mm versions of these films the 220 rolls can be loaded in subdued light. Allow about one to two weeks for delivery.
All film is fresh.
It is located here . I cut this film down myself and my cutting method is very accurate and produces a smooth cut. I can provide it much cheaper because I buy it in bulk rolls and reload it in 35mm casettes. It is an Adobe Reader File. It containts a vast amount of info on IR photography and water transmission of IR light.
