This is a collection of nature-themed picture books, combining items received with those I already owned. There may be some rare items included, as well as many retro books. (Some show wear and tear commensurate with age...) Fukuinkan Shoten: Kagaku no Tomo - approximately 70 books Sekai Bunka Publishing: Shizen no Sekai - 9 books, Kagaku Playland - 3 books Child Honsha: Sun Child Big Science - 4 books Please prioritize the images over the description for the number of books. Many are old, so there is noticeable aging, yellowing, staining, and deterioration. Some may have names written in them, markings, stickers, or red lines on the bottom. * There are about 3 or 4 books with writing or pages torn out. I thought the 12th image would show them, but "Damashikko," "Oyogu," and "Terebi ni Deta" (4 books) should be considered "extras." (So, there are actually about 82 books?) I've uploaded images of the most noticeable damage, but not everything is shown. There may be overlooked damage. Please check the condition in the images and understand that these are used books stored at home before considering a purchase. There may be overlooked damage such as deterioration, writing, or tears that are difficult to see in the images. Please refrain from purchasing if you are looking for pristine condition, are very particular about condition, or are overly sensitive. I don't think those looking for pristine condition would consider buying based on the images (self-deprecating). The images may appear slightly cleaner than the actual books, and the colors may appear slightly different. Please refrain from purchasing if you are looking for pristine condition, are very particular about condition, or are overly sensitive. I will ship the books as they are, as there may be some dirt that can be removed. Thank you for your understanding. I am not offering individual sales of the books being sold as a set. I will consider price reductions at my discretion, so please refrain from asking. * Please read my profile before requesting a price reduction. Please comment before purchasing to confirm the items. (This is required. If you purchase without commenting, please send a message saying "I have confirmed the damage and it's okay.") ☆ Please also read my profile if you have time. I look forward to your purchase. ☆*~(〃^ｖ^〃)v * I strictly prohibit the use, reproduction, or imitation of my product descriptions.
