We specially made this nib for qualified fast and comfortable work with alcohol marker. Now you don't need to wait when ink dries and can continue sketching with markers just after 5 seconds even on the smoothest paper and ink becomes resistant to other alcohol ink.
Ink isn't toxic, safe for use, not water resistant.
Pen can be used in combination with alcohol markers as well as separately for lettering, calligraphy and making titles/notes.
In the video below we show a new pen in action, we compare it with other brush-pens which are made for alcohol markers.
