I just filled my Waterman with this stuff and it is thick. It covered the nib like a paint job with no run off what so ever. Gonna have to play with this for a bit before I make it part of my "keep on hand" inks. First impression, even as thick as it appears it does flow even and wet in this inexpensive little Kultur(?).
Stay tuned for updates.

My apologies, I see there is already another thread about this ink.
