Demon Slayer: Kimetsu no Yaiba - Swordsmith Village Arc - Chapter 1: Theatergoers' Bonus First Edition: Key Visual Illustration Board The original plastic cover got dirty, so I wrapped it in plastic wrap. Because of this, the surface has slightly deteriorated, as can be seen depending on the light (photos 2 and 3 from the end). I only recommend this for those who will frame it and view it from a distance, or for cases where small children want to touch it directly. I realized that directly touching the plastic wrap is not good, so I am currently sandwiching it between kitchen paper and then wrapping it in plastic wrap, as shown in the last photo. When shipping, I will attach cardboard to one side to prevent it from bending.
