Calligraphy brush = 1008 yen ($8.54 €7.75)
My daughter bought her calligraphy brushes for the school calligraphy class. One brush cost 1008 yen ($8.54 €7.75). She bought two brushes, so the total cost was 2016 yen.
In her high school, the students learn art. There are four art courses in the school; music, fine art, craft and calligraphy. The students choose one course from four. My daughter chose the calligraphy.
Here is a sample of brush (link to Amazon).
