If you don’t know about “Kōjien" , Please check the wiki page bellow https://en.wikipedia.org/wiki/K%C5%8Djien

Detail Text : The symbolic and known Japanese dictionary “Kōjien” is now becoming a tote bag. The tote bag is big enough that it can easily and fully store A4 size papers and magazines,
with its good dimensions the tote bag is a good fit for both men and women.

Because the kanji symbols are cool, it is also a good Japanese souvenir to bring back home.

There are three items in the Kōjien series, the "livre" pouch, the handkerchief and the tote bag. Purchasing everything as a set is also recommended.
