Osaka-Kansai Expo 2025 China Pavilion Staff Pin Magnet Pin Badge Pins Shanghai China Pavilion One-Day Limited Gold This is likely the last week pin from the China Pavilion, distributed during the "Shanghai Day" event held for one day within the China Pavilion. This is a very valuable pin badge, distributed one per person only to VIP guests and China Pavilion staff, so it is rarely seen in flea markets. Especially during this week-long event, the Expo was attracting over 200,000 visitors daily, making it difficult just to enter the venue... I believe it has become valuable due to that impact and the scarcity of the pin badges. Although unused, there are some minor scratches due to its nature.
