Pilot Iroshizuku Fountain Pen Ink, Asa-Gao

Asa-gao is yet another fabulous blue ink from the Pilot Iroshizuku fountain pen ink collection. Asa-gao is inspired by the morning glory flower. This ink is a true, deep blue.  It is very similar to Iroshizuku Tsuyu-Kusa (pictured below), but one shade darker.  This ink is great for everyday use.
