The JJC FR-1 Film Retriever is specifically designed for 135 films (35mm) to pull the film from cartridges easily. It is made of eco-friendly ABS & PET material, making it durable and deformation-resistant. With its three-sheet design, you can extract the film without too much effort, and the slide sheets are smooth and polished to protect the film from scratches. It can be used in daylight without the need for darkroom facilities, and it's easy to operate even for beginners due to its simple structure. Using the JJC FR-1 does not affect the functionality of the film.
