“Maikake” is an apron. It’s meant to keep your clothes clean or to protect yourself. The old Japanese work apron “Maikake” is made of canvas and is durable. It is used in business sites such as liquor stores and rice stores, and on the other hand, it prints advertisements, so it seems that it was distributed to the people concerned.

This “Maikake” seems to have been given to the predecessor who shipped seaweed to Tokyo.
