It seems this school didn't use textbooks much, so I believe they are in relatively good condition. (Added "New Chemistry Materials") I'm not sure if QR codes, etc., are currently usable. Some items are unused, some have marks from being opened once or twice, some had names written in permanent marker that were completely removed with nail polish remover, and some have exteriors that aren't quite new, but overall, they are in good condition. I didn't find any writing in the books except for one. (Please forgive any oversights) "Modern Japanese Language" seems to have been used in two lessons and has some writing. It was written in pencil and Frixion pen, so I erased it with an eraser. The printing around the erased areas is slightly faded. I'm currently considering selling them as a set.
