FEFCO 0426Mailer
Double-front box with lid dieline
A one-piece die-cut box whose front rolls over into a double wall locked into the base, with the corner ears trapped inside it. The lid’s rounded ears drop inside the ends and its tuck slides behind the front. A parametric template — change the length, width and height and every panel, tuck and glue flap is redrawn to match.
