Masu box

How to fold an origami masu box

Paper
One square sheet of paper.
Preparation
No cutting or gluing is included in these folding steps. Begin with “Crease the vertical center”.
What you will make
An open-top box. A lid is not included.

Make an origami box by bringing all four corners to the center and creasing the walls. Raise the left and right walls first, then fold the back and front corners and tuck their tips inward. Align the creases carefully before raising the walls to make the bottom corners easier to follow.
