Ministop "Infinite Pudding"
It seems that you can continue to eat indefinitely

At each Ministop store, the popular "-Infinitely delicious food-Infinite pudding" that was sold from the end of last year to the beginning of the year is re-appearing. It has been on sale since February 14th (Tohoku will be released on February 15th).

This is a hearty pudding that was developed with the concept of "deliciousness that you can continue to eat forever". The texture seems to be hardened. The price is 348 yen (tax included).
