This is a non-sale can badge from the BLUE OCEAN DOME at the Osaka-Kansai Expo. I received it at the Blue Ocean Dome when I went in September. My child wore it on their cap all day that day. After returning home, I stored it in a dark place. The diameter is approximately 6 cm. I plan to send it via Yu-Packet Post Mini. Please check the condition in the photos, and please understand that this is a used item, has been stored at home by a private individual, and the shipping method before purchasing. - Design: BLUE OCEAN DOME, ZERI JAPAN, SARAYA - Colors: Blue, Red, White - Type: Pin badge - Event: EXPO 2025 Thank you for viewing.
