They are tabbed, pocket-style file folders, scaled down to accept either 35mm or roll-film format negatives
Organization becomes automatic; You can file by job, subject or roll number, and label needed information on the folder index tab; As digital files take over pre-viewing and cataloging tasks, originals still need to be kept in safe storage and appropriately organized. Remove them from plastic pages, especially PVC vinyl ones, and store them in archivally safe sleeves, folders and boxes.
Each folder expands to easily hold about a dozen strips of negatives or un-mounted transparencies
Folders hold 6-frame (or shorter) strips of 35 mm film and 2-1/4" film in strips of up to four exposures per strip, depending on format
Folders are constructed of heavyweight 7-point card stock in cream color
