The real blank at this size, folded by the same engine as the studio. The artwork is a sample from a fictional brand — swap in your own in the editor.
Slot-lock document folder dieline
A cover and a front flap close over the contents and lock with a tongue through a slot: retaining side flaps make a three-flap folio, glued gussets make a file pocket, with optional capacity. A parametric template — change the length, width and height and every panel, tuck and glue flap is redrawn to match.
