Is that Platinum carbon black or the standard black ink? It looks like the water based dye standard black ink bottle... 😮

The chao kuro is the ink I would purchase but the price for a 60ml bottle is astonishingly expensive.

I see no need for the Carbon Black after this video. However, I usually use my Rotring Isograph pens when I want black ink because I can use Rotring’s 100% waterproof India ink. It looks absolutely amazing on paper.
