This is a special, non-commercial tote bag distributed exclusively to visitors of the null² dialog mode at the Osaka Expo 2025. There are two bags. These limited-edition bags feature a design by null² and include a signature from producer Yoichi Ochiai. They are not sold in shops. They were only used when entering the pavilion and have not been used otherwise. Please refrain from purchasing if you are overly concerned about minor imperfections due to amateur storage. They will be folded for packaging.
