Negative Film Storage File Each refill holds 6 strips, with 6 strips on the front and 6 on the back, for a total of 36 negative film strips. I purchased several of these about 20 years ago, but they have been stored unused since I switched to a digital camera. Although unused, the refill sections have wrinkles due to aging. Also, they appear to have slightly yellowed. I would appreciate it if you understand that this is a used item that has been stored by an individual for a long period of time.
