The ruler is not for sale. If you have no questions, you can buy it immediately. I opened it to check the design. Only the strawberry on the bottom right is from 2024. The others are from when I bought ice cream in December 2025. Please note that I may change the shipping method from Rakuraku Mercari Bin to Yu-Yu Mercari Bin. I will pack it with bubble wrap within the 3cm limit. I would appreciate it if you could buy them as a set, not individually.
