This sturdy ring binder with four rings was introduced by Kenro specifically for storing negative storage pages. The negative files of, for example, Kenro are wider than the standard A4 format, so a normal A4 ring binder is not suitable. This ring binder is therefore also slightly wider so that negative files fit perfectly in the storage binder. The ring binder keeps the weight of approximately 100 to 150 Kenro negative storage pages, regardless of the film format (35mm or 120).
The backside of the binder has a writable label with date indication and a possible description of the contents.
