We offer a wide range of acid-free, archivally safe and transparent sleeves made of polypropylene and polyester, which are suitable for the professional archiving of photographic collections and documents of all kinds (e.g. DIN A4, DIN A3). With the help of the lateral filing edge, all sleeves can be stored in an archive-friendly manner, for example in the "Reflex" archive box, standard folders or hanging files, depending on the model.
