Pilot Iroshizuku tsuyu-kusa is a bright blue ink that translates from Japanese to Asiatic Dayflower. It leans less purple than asa-gao.
Tsuyu-kusa flowed very well through my pens and felt nicely lubricated when writing across the page. Not at all scratchy. I felt it flowed quite wet. I saw some nice shading and you might occasionally see a slight red sheen in a heavy blot on coated papers.
I didn’t notice any skips or hard starts when I put the uncapped pen down to do swab tests, dry times and water resistance. I didn’t see any feathering on the papers I wrote on.
Available in attractive Pilot Iroshizuku 50ml glass bottles from The Writing Desk
