I bought a 400 yen product that said "set of 4 cards" because I thought it was cheap looking at the cards and the number of cards, but after I received the product, I was told that "the number of cards written in the product name was a mistake. After I received the product, I was told that "the number of cards mentioned in the product name was a mistake. The number of cards I received was 2.
I am very sorry.
The response time was fast, as I received my order within 24 hours, although it was a weekday
