Greetings, I have been in contact with Archival Methods regarding storage boxes measuring 8"x18" for both negative and contact print storage. See this link http://www.archivalmethods.com/Product.cfm?categoryid=29&Productid=122 if you have an interest. Minimum order is 100 boxes @ $28.80 per box plus shipping. Box is black metal edged and measures 1.5"H x 8"W x 18"L and has a drop front feature. I'll start by committing to 10 boxes and organizing the logistics of the purchase, let's see if there is enough interest out there.
