“Gordigiani” folder boxes are made from Duralong Special conservation board, ideal for vertical storage of loose documents or documents put inside folders and envelopes. They are produced in one piece with two large flaps and four small flaps. Thanks to the numerous creases of the flaps, they offer a great modularity, adapting without problems to the different thicknesses of the content. They are designed to be completely closed and then to protect the contents from dust. The closure is possible with the insertion of the herringbone cotton tape (not supplied) which can be inserted easily in the cracks present.
