This is "Kodomo Challenge Baby: Let's Play in the Sand" and "Mii-chan, Good Girl, Good Girl," which I took in the 2020-2021 academic year. I used to read them repeatedly and they were my favorite books, but I no longer read them, so I am selling them. ■ Condition Since these books were read by a child, both have many scratches, stains, scuffs, and folds. Therefore, please refrain from purchasing if you are concerned about the condition or are a perfectionist. 【Let's Play in the Sand】 In particular, although it may be difficult to see in the photos, there are noticeable issues such as the fold in the "Digging and Digging" mechanism and the bottom of the page, the tear in the lower center and the edge of the back side of the pop-up mechanism of "Sand Mountain," the fold and peeling/stains at the bottom of the mechanism, and the yellow stain on the top (see photo 5). 【Mii-chan, Good Girl, Good Girl】 In particular, there is a large vertical fold on the last page (see photos 16-18). Although it is difficult to see in the photos, there is a distortion or warping on the last page when viewed from above (see photo 19), so please check it as well. Also, please note that the fur has a rough texture. Also, both the front and back covers and each page have stains, small scratches, and scuffs that are difficult to see in the photos. Therefore, please check the condition and design in the photos. * Please consider purchasing only if you understand that these are items used by a child, stored at home, and are used goods. ■ About Packaging and Shipping After putting them in a waterproof bag, I will wrap them in cushioning material and ship them via Nekopos in a bag (paper or vinyl). Please note that I will use recycled materials for the cushioning material and the outer bag.
