This simply designed folder fills a nice gap in sleek, minimal, and sturdy folders for storage and handling of thin items.  The first flap is full coverage, folding in to completely protect the contents.  The smaller top and bottom flaps are partial coverage to create a gap for the Dual Lock coin to sit which provides strong positive closure.  

Dual Lock is similar to Velcro, but is stronger and does not wear out the way typical hook and loop fasteners do over time from repeated use.

All 3-dimensions (length x width x depth) are fully customizable as are the interior flap sizes.  The front flap will always be full coverage.  This box style is designed to be used with our E-flute or E-PLUS flute Heritage® Archival Corrugated Board.

Great as a presentation option or for long-term storage of books, photographs, documents, prints and more.

All boxes are cut onsite in Brooklyn NY and our typical turnaround time is just a few business days.  For more information and pricing please email or call (, 212-219-0770).
