5. Place the bottom tip on the marked spot. Only press down on the crease along the marked line.

6. Bring the upper tip down and thereby open up the shape.

12. Carefully push the shape together from all sides. Done! Now you only have to repeat this process 47 more times ;-)

13. That's what it's supposed to look like from the inside.

14. Finally, glue a self-adhesive magnet S-20-01-STIC inside on the box bottoms.
