I finally got this bottle. This is one of the Sailor ink that is still produced in Diamond shape bottle and still stayed at 2000 yen price.
Standard drying time for blue inks. This bottle made me think about Diamine Marine but 2 shades darker. Very saturated that didn’t have much shading. Initially I thought there’s no sheen for this bottle but later saw the red shining sheen at the edge. Low water resistant, the ink flow was very wet with the BB nib but didn’t bleed through iPaper UCCU or PaperOne 70gm.
CP value: 70/100, good color, but considering how hard to buy it…. well, I’ll open a bottle of Marine and reduce the solvent.
