Kiso Mondai Seikou II・B Obunsha First Edition: February 10, 2020 Reprint: Published in 2022 I purchased this several years ago and stored it in a dark place at home. It is almost unused, but there is a bend mark as shown in the third photo. Please refrain from purchasing if you are sensitive to the condition, as it has been stored by a private individual. Instant purchase available ⭕️
