This is a set of two novelty notebooks featuring the SoftBank and Yahoo Mobile "Father Dog" character. Size: Approximately 21 x 15 cm The inside is in good condition and usable, but because they were stored together at home for a long time, there are some whitish marks where the covers were stuck together. It's difficult to see in the photos, but please check the third photo. Please refrain from purchasing if you are concerned. As stated in my profile, I may change the shipping method from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. Also, I often use recycled packaging materials. Thank you for looking.
