This might be the most standard ink I can get easily – pretty much every book stores in TW carries it. The bottle changes from time to time but the color is still the same.
Very standard – standard drying time, standard limited water resistant, standard flow, and standard penetration/no bleeding. However, this ink has the problem that all blue inks have to face – color fading out. As record, this photo is taken 2 months after initial review and the color had faded slightly already. I’m not sure how long the strokes will last and I’ll keep you updated.
CP value: 70/100, considering how easy the color fading and how easy to buy one….
