The Fixation series is a collection of pigmented, waterproof fountain pen inks. They're known for their high quality, vibrant colors and are high resistant to fading and bleeding. They feature colors often inspired by Japanese nature and culture, with names referencing specific plants or elements like "Yuki" (snow) or "Hiiragi" (a flowering plant). The colors in this series are deep, saturated, and produce wonderful shading with a Japanese aesthetic.
