I’m on my second bottle of this ink. I think that says a lot. There are very few inks I have bought it again after the first bottle ran out.
The other one is the black Iroshizuku ink; mostly because I like to have a bottle of black ink.
This was also the first Robert Oyster ink I got. He makes some really cool inks. Not loving the bottles though. And in my experience they are like 95% of what I get from Iroshizuku.
The color is basically something that looks very similar to the orange you see on The Pen Addict. I like it a lot, and it is the ink I’ve kept permanent in my FC Pocket 66 since I got the second bottle.
