Osaka-Kansai Expo 2025 Japan Pavilion Limited Edition Algae Kitty Secret Pin Badge "Windmill Diatom". I have opened it once for photography. Unused, with backing card. I will also include the bag, but since it has been opened once, please refrain from purchasing if you are concerned about the details of its condition. I will pack it with measures to prevent breakage and water damage, and ship it via anonymous Yu-Yu Mercari delivery.
