These boxes are perfect for archival storage of prints, drawings, newspapers, maps, textiles, and other flat collectibles.
Sizes listed are inside dimensions and are 1/2" larger than those listed on both the length & width. (ex: 8" x 10" is actually 8.5"x10.5")
The drop front on the box allows for contents to slide out flat when the cover is removed. Our boxes are unique in that the drop front side travels in a channel on the corresponding size, making a stronger box. Base and lid are cut from our exclusive Heritage Corrugated Board and produce the finest archival storage box on the market.
All boxes are shipped flat for economical transport, and are easily assembled without glue or adhesives.
