This is a 2025 desk calendar from SPring-8-II at RIKEN. I received it from a friend, but I won't be using it, so I'd like to give it to someone who enjoys scientific research. It was only opened for the photos, and it came with an original keychain. Although it is new, please understand that it has been stored at home before purchasing.
