Onyx Black is a black ink with a wet flow. This is not a pitch black ink, if you look closely, you will notice a little shading. But for general purposes, this is black enough for me. I noticed this ink takes a while to fully dry. This ink is easy to clean out of the pen.
The writing samples below were written with a TWSBI ECO-T medium nib.
