Review on 🖤 Premium Yasutomo Black Sumi Ink (Bokuju) 12 oz. - High-Quality Japanese Calligraphy Ink by Shantel Griffin

Yasutomo Sumi Green Bottle is by far my favorite fountain pen ink. I need to test more black black (which I believe) and I've used a lot of them. In fact, it seems to have texture. It dries semi-glossy and is easy to spread. To be honest I'm not sure what makes him different from others. The only thing I'd like to add is that I've never diluted it with water, so I can't comment on ablutions. For me, this is my go-to high contrast ink and it doesn't seem to "smudge" as much as other heavy black inks. I also never noticed the "toxicity" that other reviewers have mentioned. If anyone has any information I'd appreciate feedback as I've been using it for years.
