Archival-quality storage box holds 17x22 inch prints with drop-front access and metal-reinforced corners
This two-piece storage box is built for the safekeeping and conservation of photographic prints up to 17x22 inches. Constructed from archival-quality fiberboards, it is acid-free and free of lignin, ground wood, sulphur, and recycled chipboard. A patented Dual Chemistry design uses an alkaline buffered exterior and a neutral non-buffered interior separated by a polyester barrier. Metal reinforced corners protect high-wear areas for added durability.
The drop front design on the bottom section allows prints to slide gently in and out without forceful finger intrusion, unlike flat sleeves that require pinching. The removable top section provides full access for organizing or viewing entire collections at once. This upgrade is worth it when handling valuable or fragile materials where physical contact and environmental acidity pose long-term risks.
The buffered exterior continuously neutralizes atmospheric acids and pollutants that migrate through storage environments over years. The neutral interior ensures no alkaline reserve contacts the emulsion directly, preventing unwanted chemical interaction during decades of storage. Metal corners maintain structural integrity when boxes are stacked, though heavy items should not be placed on top to avoid crushing the contents.

The box is designed for 17x22 inch prints with a 17 1/2x22 1/2x3 inch construction, providing a precise fit for standard large-format photographic materials.
Separate the removable top lid from the base, then lower the front panel of the base to slide prints in gently; a common error is forcing the lid on before the front panel is fully closed.
The patented Dual Chemistry design uses a polyester barrier to separate the alkaline exterior from the neutral interior, maintaining long-term archival protection without scheduled replacement.
