We manufacture our archival storage boxes in Brooklyn, New York using our exclusive Heritage Corrugated Board. This board sets the standard in the next generation of archival corrugated board. Greatly exceeding the quality of other boards available on the market today, and passing much more stringent testing for permanence than simply the Photo Activity Test, this is the next generation board available today. With great board comes great boxes. Our unique designs, both custom and standard, are the highest quality and strongest available. We We believe that a lay-flat design (meaning boxes are shipped flat and are assembled without glue) produce a stronger and more secure box, which is less prone to rust and is less likely to break over time. Can't find the size or style you are looking for? Most of our enclosures can be built to custom fit your needs at as few as 1 box. Give us a call or email us and we would be happy to assist!
