Thanks so much for taking a photo. It's a beautiful set! I like the little porcelain dishes
xd So I'm guessing the ink stick doesn't make permanent ink then? I'm glad to hear that.
There's so much to choose from, maybe I'll just take a gamble and choose whatever. I'm just trying to find a very opaque black, maybe they can all make that. I could just use less water and grind more.
I did some samples using the Chung Hwa here.

After I rinsed the brush, I made the sample on the left.. so you can see it is not evenly black, some parts are darker than the others. I also rubbed a damp kleenex over it once dry, so you can see how little it smudges.
The bottle I'm using is the same as the one here

Its ink is not as dark as I'd like it to be... It also has a somewhat strong smell. But I often see it used for Chinese calligraphy, there are many videos of it online
