This is a limited edition piece made 30 years ago. It is inscribed with the name "Shichiten San'yo" (Seven Sable, Three Goat). <Description> The excellent bundling and resilience of sable hair, combined with the suppleness, tenacity, and ink-holding ability of goat hair, allows for the creation of lines with rich expression. <Hair> A 70:30 ratio of aged, high-quality sable tail hair and the hair from the jaw to chest of male goats is used.
