A set of pin badges and stickers from the 1970 Osaka Expo. This item was in the possession of a family member who worked as a staff member. It is likely a non-sale item. The size is about 1.6cm. Although unused, there is natural deterioration due to amateur storage. The surface is clean. There is a slight rust-like discoloration on the back. The bag is not clean, but it was stored as a set, so I will include it. Please consider.
