[USED] Demon Slayer 2-book set

Demon Slayer: Kimetsu no Yaiba - The First Illustration Artbook Demon Slayer: Kimetsu no Yaiba Illustration Record Collection Vol. 1 This is a set of two books.

They have always been stored in their boxes, and the first artbook has a crease on the back corner as seen in the photo.

When I flipped through them, there was no dirt or anything, and they are in good condition.

Due to shipping costs, I am not considering lowering the price.
