About the Open Envelope design

The outline climbs from a flat base to one sharp peak at top center, every other corner rounded off. Inside it, a second pair of diagonals drops from the upper shoulders to a V whose point falls about two thirds of the way down the height, and the steel caught between the two pairs makes a broad chevron several times heavier than the thin band tracing the sides and base. Those upper shoulders are the only places where three edges of steel converge.
