How to fold the pen container

The paper folding method of the pen container comprises the following steps:

Step 1: Prepare a thick square paper, the size is preferably above 17 cm, and fold it diagonally to form a cross crease;

Step 2, fold the opposite sides into four equal parts, fold the four sides up along the crease, and then unfold;

Step 3, fold the paper into a big triangle along the diagonal, fold the lower two corners into a triangle obliquely upward along the crease, then fold the paper into a big triangle along the other diagonal, and fold the lower two corners into a triangle obliquely upward along the crease;

Step 4: Finally, support the four sides along the crease and fold it into a cuboid.

Preparation before origami:

Step 1: We need to prepare a relatively flat object as an origami table.

Step 2: When folding, be sure to fold from your direction to the distance (because there are many video origami tutorials for your convenience, most of them keep the direction of the paper unchanged. )?
