This is a sticker that came as a bonus with a calendar for Kazuo Iwamura's picture book series, "14 Mice." It is not for sale. Each sticker is a circle with a diameter of about 2 cm. The stickers feature the 14 mice: Okaasan (Mom), Otousan (Dad), Obaasan (Grandma), Ojiisan (Grandpa), Ikkun, Nikkun, Sacchan, Yocchan, Goukun, Rokkun, Nacchan, Hakkun, Kuncchan, and Tocchan, as well as plants, insects, and other small animals, and various small items that appear in the picture books. They are very cute! There are 35 stickers in total. The picture book author, Kazuo Iwamura, sadly passed away, but the series is still very popular with children. My own children enjoyed discovering all the little details. For fans of Kazuo Iwamura's picture books, what do you think? Please consider purchasing them.
