The tan Drop-Front Archival Storage Box from Archival Methods protects and stores digital and photographic prints, matted or not, within its 1.5" deep hinged box. The box is constructed from heavyweight, archival-grade boxboard that has a matte-laminate coating for water resistance. Removing the box top reveals a hinged drop-front panel on the front long side so you can safely insert, remove, or examine contents in the the bottom section of the box.

The metal-reinforced corners of the box top are treated with a black polyester coating and a wax-free polyester finish, to be anti-corrosive. The clamps give rigidness and strength to the box so you can stack multiple boxes on top of each other. The box is PAT passed, which means it is suitable for long-term storage.

Q: 9. I purchased this product about 4 years ago and never opened it. Would it still be good to mix and use today?

A: If one purchased the Photographers' Formulary TF-4 Archival Rapid Fixer for Black & White Film & Paper ,and never opened it up, and stored it in normal temperatures,(not too warm), it should still work fine. Just to make sure it would be good to do a test in the darkroom, by fixing a paper sample for the normal fixing time, and then turn the lights on to see if it will fog.

Q: 10. How does this compare to the Voigtlander 50mm f1.2?
