I haven't used these much because I was busy with work. There's a thread only for Kazuhitatatsuya's picture books. I used this a few times because you can play with it on your smartphone. These are picture books you can play with using the "Oshaberi Shimajiro Pen." You can hear sounds if you have the "Oshaberi Poppon." These are from the 2024 course, so they are relatively clean. If there's anything you'd like to buy separately from these, I will accommodate you. m(__)m Yu-Yu Mercari Delivery Service
