Enigma US Letter Quarto Binder
The Enigma US Letter Quarto Binder is specifically for the US letter pockets and storing this type of documents
(See our Enigma archival US Letter Quarto Pockets here)
This binder features a quality 3 D ring mechanism* for secure storage and a frosted clear hard but flexible polypropylene 1200micron cover allowing the first page to be viewed through the cover.
* D ring mechanisms are fitted inside the rear cover keeping your pages in line. Far better than using O ring mechanisms.
