Purchased new from Nihon Gakko Tosho Co., Ltd. Volumes 1-36 are complete. Volumes 1-15 (excluding 14) are in near-new condition, but please note that there are writings in volumes 16 and onwards. ✨There's a bonus! Please look forward to it!✨ I hope this will be helpful for those involved in early childhood education! ✨Thank you for looking!✨
