Sailor's Shikiori ("Four Seasons") inks feature vibrant and unique colors inspired by the natural beauty of Japan's changing seasons. This double-sided brush pen features the same ink color as in the Shikiori fountain pen ink line, with an expressive felt tip that is perfect for artwork and calligraphy. The brush tip is covered by a cap accented with the ink color, while a smaller cap on the end comes off to reveal a fine marker tip.
