Used for practice. ○ Creases and stains on the main paper (Image 4) ○ Stains on the back (Images 5, 6, 7) ○ Stains on the inner box, damage and writing on the outer box (Images 8, 9, 10) I think it can still be used. How about for practice? Please take a good look at the images and those who understand, thank you.
