Detail
Duo-Colour fountain pen inks from KWZ, specially made for Cult Pens' birthday.
The colour varies, depending on whether it's wet or dry, and the absorbency of the paper it's used on. The Brown/Green ink starts off green, but turns more brown as it dries, whereas the Blue/Grey ink is more of a purple when starting out, which then disappears. They certainly make writing notes just that little more interesting!
KWZ Inks came about as the result of Konrad Zurawski, a graduate of the Faculty of Chemistry at the Warsaw University of Technology, following his passion for fountain pen inks, and making the products he wanted to see and use.
60ml bottle.
