Shinken Zemi (Benesse) Challenge 1st Grade 2019, 2nd Grade 2020 Waku Waku Science April issue to March issue Challenge 3rd Grade Waku Waku Discovery Book Special Edition - Unknown Dinosaurs Complete set of 25 books About 4 or 5 books have creases. Although I believe my daughter looked through all of them once, she viewed them as educational materials and felt obligated to read them, so she didn't look at them repeatedly. About half of the tear-out items used on a few pages within the booklets are missing. The top row in photo 4 shows the items that have been torn out and are missing, or that don't have the supplement. 11 books The bottom row has not been torn out. 12 books Even without the items, they can still be enjoyed as reading material. Would these be suitable for a child interested in science? Please understand that these are used items and have been stored at home. If you can use Eco-Mercari delivery, please let me know. Thank you. - Series Name: Waku Waku Science - Number of Volumes: Complete Set Thank you for looking.
