I sometimes go to the post office to buy a special stamp.
The Nagano-Kanazawa route of the Hokuriku Shinkansen Line began services on March 15 this year.
The other day, I bought its special stamp of the Hokuriku Shinkansen.
It was included in such a fashionable sheet.
There are three types of the special stamps which are national version, Hokuriku version and Shin-Etsu version.
