My thanks to Ana of The Well Appointed Desk for the ink sample.
KWZ Chicago Blue is a standard dark blue ink. It is mostly flat and doesn’t shade very much. It does have the standard KWZ ink scent and so if you don’t like it, stay away. This colour feels excellent for corporate use. Also if you are looking to buy a bottle of KWZ Chicago Blue, you’re probably out of luck. This was made exclusively for the Chicago Pen Show 2017.
