A business card file that records the memories of encounters.
It is a business card file that can record information when you meet and revive your memory every time you look back.
If you file the names and shop cards you have exchanged, and record (= Log) the date you met, the characteristics of the other person, and the conversations you exchanged, you can manage your business card and information together.
The order of the refills can be swapped, making it easier to organize the names.
