The advantage of the Archival Methods 16.25 x 10.75 x 5" "Pop Lok" Box is that you inventory these boxes flat until you need them, saving valuable space in your supply room. When additional documents arrive for storage, just pop open the flat box, fold over the flaps and everything locks securely in place, providing a rigid and fully enclosed archival document box.
Now, there's a box that let's you store your valuable papers in archivally safety. Archival Methods has designed a storage box that not only stores papers, but that stores itself when not in use. Empty boxes store flat on top of each other and "pop" open when needed.
Stores flat until needed, assembles in seconds
