iroshizuku - kosumosu

Pilot Iroshizuku Kosumosu is a cheerful, bright pink ink reminiscent of cosmos flowers, offering low shading, a tiny gold sheen visible mainly on Tomoe River paper in large swabs, and quick drying around 15 seconds. It flows smoothly with good legibility, minimal feathering on quality paper, and a happy, spring-like character that lightens slightly when dry. This well-behaved ink suits everyday writers, journalers, and those seeking a fun, vibrant pink without neon intensity.[1][3][6]
