What is the shelf life of Entrada Rag stored in original boxes?

Under ideal conditions Entrada (and our other Moab papers) should last for years on the shelf. They would need to be in the original clear bag, within the box, stored flat. Beyond packaging, paper is affected by humidity, airborne contaminants, heat, and other environmental factors. Visually inspect the sheets before printing. If you see any discoloration of the sheet(s), especially around the edge, or excessive edge curl, I would recommend replacing them instead of printing.
