This is a series of ink reviews "blues reviews" covering nearly all the blue inks in my collection that I haven't yet reviewed. This ink is one of the custom inks Sailor creates for certain stores in Japan. This ink was created for the Bungbox shop in Japan. I'm not sure if these inks are available any longer. I obtained my bottle during a short time when Vanness had this ink in stock.
Tested on Mohawk via Linen, Hammermill 28lb inkjet, and Tomoe River.
