This is a tuck-top box — in the trade also called an airplane box. It is die-cut and creased from a single sheet of board, so there is no separate lid, no glued corner to fail and no assembly line needed before you can use it. The box ships flat and folds into shape by hand.
For sushi takeaway that shape is doing three jobs at once. The board walls stand up to hold a full set without sagging, the lid tucks shut so nothing shifts on the way, and the front opening lets your customer lift the lid in one motion and see the whole arrangement.
There is a second surface most packaging wastes: the inside of the lid. On this box that face is printed — so when the lid comes up, your logo comes up with it.
