It's okay. Not great but not bad. The black isn't the darkest. It's more of a
purple black. And the ink bleeds a little on cotton paper. But it seems to flow
well. It's a decent black ink.
I am not sure why previous reviewer said it was an OK black. In my expereince of
using this ink for 20 plus years it is one of the BEST black ink avaliable. And
I have used many of them. The only black that MIGHT be slightly darker is
AURORA.
