It takes one sheet of square paper and 13 steps to make the basic masu-style box. A second sheet of square paper, the same size as the sheet used for the box, is cut up into two equal rectangles. It takes one of these rectangles and 4 steps to make the wedge base. It takes the other rectangle and 5 steps to make the lid fastener. It takes an additional 3 steps to insert the wedge base into the box and to secure the lid closed with the fastener. Hence, 25 steps in all for the completed model.
