This is a great deal on a set of two.
It can be safely used as a flavoring agent for handkerchiefs and oshibori, and as a flavoring agent for foods such as tea, liqueur, and confectionery.
In addition, it seems that many people use it as an aroma oil, such as the aroma of the room/toilet, and a few drops in the bath when tired.
Enjoy the refreshing mint scent for a relaxing time.
