Shooting ink with a ratio of 3 parts pine oil to 7 parts oil. Purchased on the recommendation of Mr. Morita of the Sesshin-kai. In his later years, Mr. Imai used only this ink. The brush is Taikan's calligraphy and painting brush. 14.5 x 3.4 cm. This is a Tang ink that easily produces ink color. It is rarely sold commercially.
