In this campaign, if you wear a cow-patterned item and go to the store and say the slogan "Day of the Ox", you will get one small-sized ice cream. Since the image character of the brand is "cow", it is said that it will be held on "Day of the Ox".
The "cow pattern" items that you can wear can range from goods to full-body cow patterns. Instead of the soaring price of "eel", it may be good to spend "Day of the Ox" with ice cream.
