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.
Slotted box with eared inner lid dieline
A full-overlap slotted box whose front flap is an inner lid: its ears tuck inside the end walls to hold the contents before the end flaps and the outer flap close over it. A parametric template — change the length, width and height and every panel, tuck and glue flap is redrawn to match.
