Myaku-Myaku of EXPO 2025 2025 Osaka-Kansai Expo 3D Rubber Mascot Key Chain Myaku-Myaku Oekaki-san Myaku-Myaku I don't know the meaning of "Oekaki-san." Purchased at the official store inside Shin-Osaka Station. The category says "acrylic," but this is not acrylic, so it bends if you squeeze it hard. I couldn't shop at the Expo venue, so I bought it at the official store inside Shin-Osaka Station. I only recently learned that there was a shop inside Shin-Osaka Station when I used the Shinkansen. At that time, I didn't have much time and there was a long line, so I went back to buy it specifically for the shop. New, unused, unopened.
