Sailor Shikiori Fountain Pen Ink (20mL) - Yonaga

This is, to me, the quintessential dark blue ink. It’s less blue than say Diamine Tudor Blue but not quite a blue-black. It is highly saturated - more than the Iroshizuku inks, for example.

And the flow and writing experience are just about perfect.

I will buy more inks from this line. The value seems amazing.

Yonaga is a rich, dark blue that is reminiscent of Diamine Oxford Blue and Herbin Bleu des profondeurs. Flow is excellent. This is a true blue ink, not blue-black.
