This is an eco-bag purchased at the Belgian Pavilion of the 2025 Osaka Expo. It uses a heat-retaining aluminum vapor deposition material. I used it only once to carry items purchased at the Belgian Pavilion. It's in excellent condition with no signs of wear. How about a memento of the Belgian Pavilion? Please purchase only if you understand that it has been stored at home. It will be shipped in a compact form.
