This is Swimmer. This is another Hokuriku story.
When I visited Toyama Prefecture, I bought these sweets as a souvenir.
I was very interested in the design of the wrapping paper, which had a trademark registration number blended into the design in a cute way, and it was a very interesting gift so I picked it up.
It is a very casual and eye-catching way of asserting the right to use the trademark.
