I found a conspicuous item at the Tobu Department Store / Ikebukuro B1 event store. "Carp cap oat cookie" with dazzling bright vermilion. The price is 864 yen (tax included).
This is a set of oat cookies in a paper hat package. Contains 10 cookies.
Oat cookies, which are rich in nutritional value among grains and contain a lot of dietary fiber and minerals, and plenty of "freshly ground almonds" (about 3 grains per piece) .. Compared to ordinary wheat cookies, it is less dull and has a crispy, timeless taste that makes you just keep eating.
The carp-loving package can be used as a hat for children by cutting the bottom part with scissors after eating. I also tried it on, but it was unexpected. It doesn't fit well, but I think it's okay for adults to use it as long as they watch baseball at home (probably).
"Carp cap oat cookie" filled with carp love and oat cookies. It is possible to purchase mainly at each Backen Mozart store in Hiroshima prefecture, at special events stores, and by mail order. For details on how to purchase, refer to the official website.
