1, prepare two different sizes of square paper, one of which needs to be 1 cm longer than the other side, the larger one is made into a box lid, the smaller one is made into a box body, the folding of the two is exactly the same.

2. Fold one of the squares along the diagonal, then unfold and reduce to a square.

3. Fold the 4 corners of the square towards the center point and fold into a smaller square.

4. Fold each of the four sides of the small square toward the centerline, all pressing out a deep crease.

5. Open one pair of opposite corners of the small square and stand the other two opposite corners up along the crease, perpendicular to the ground.

6. Bend the two open corners upwards along the crease as well, then fold inwards and flatten. Half of the packing box is now complete.

7. Do the same fold for the other square. Snap the two boxes together, and you have an exquisite packing box.
