Dorcus hopei binodulosus = Japanese Stag Beetle
I thought I'd reviewed this ink a long time ago, but I never did. So here it is now.
This ink is for lovers of black inks. It is one very seductive bug. In a number of Asian countries these creatures are kept as pets. However they only live for four months as a beetle: their larval stage lasts about a year.
This is a black with good shading. On TR is has amazing green sheen, especially when wet. I'm very happy I have a bottle of this. It seems like there could be some water resistance, but as always take care in that regard. The color ink droplet is amazing.
