Fast Delivery relieves pressure

When in the middle of a large project, it is not the time to find a shortage in supplies. We were in the beginning of identifying over 14,000 rail negatives when it appeared that the file separator card supply was not adequate to last until a request, via purchasing, which could be processed and shipped. B&H in New York, was found to have a warehouse in Texas about 35 miles away, and delivered 1,000 cards the next day. We also saved on the price over the normal supplier. Two Gold Stars for B&H!

I would buy this product again.

I have been shooting with Polaroid film from the Impossible Project, and was looking for an archival product to store the fully processed images. I find these envelopes have worked with all film sizes (Spectra, SX-70, 600).

How many sleeved 4x5 sheets of film can each envelope hold? I need envelopes that can hold 6-10 sheets in fold flap sleeves
Asked by: Steven
It's generally recommended to store only one sleeved sheet per envelope in the Print File NP45 Paper Envelopes to ensure archival safety (avoiding scratches or pressure damage), ease of access, and proper fit within fliptop storage boxes.
