Caso 1235 professional slide set 1 (50x foil bag 20 x 30 cm, 1x roll of film 20 x 600 cm, 1x roll of film 30 x 600 cm) (household goods)
slightly more expensive films, fulfill your purpose very well, I do not use them soooo many times, so I bought the recommended bags for equipment, they may well use multiple, are easy to clean and are very stable.
