Pilot Iroshizuku bottled ink is a premium line of fountain pen inks inspired by the natural beauty of Japan. The name Iroshizuku translates to "droplets of color," which perfectly reflects the vivid and carefully crafted hues offered in this collection. Each color is derived from elements of Japanese nature, such as flowers, seasons, or landscapes, resulting in a range that is both artistic and functional. The ink is known for its smooth flow, vibrant pigmentation, and excellent saturation, making it a favorite among fountain pen enthusiasts.

This ink is formulated to be both water-resistant to a moderate degree and highly legible, suitable for everyday writing as well as special calligraphy projects. The 50ml glass bottle is elegantly designed with a wide base to prevent tipping and a convenient filling mechanism that makes refilling pens easy and mess-free. Additionally, the ink is acid-free and safe for most fountain pens, minimizing the risk of clogging or corrosion.
