Sailor Dipton Blue flame is part of Sailor's ink collection Dipton for dip pens. Dipton is named after the English word dip, and the Japanese word "ton" (an onomatopoeic word that comes from the sound made when a pen nib touches the edge of an ink bottle). Blue flame shifts between green, purple, and dark blue with a lot of sheen.
Also available in several other colors.
Note! Suitable only for dip pens (not for fountain pens).
