The Tombow BK-LP03 Rollerball Pen Refill is a liquid rollerball refill that is designed to work with Tombow pens, like the Zoom 505.
The naming of the refill is rather confusing with the BK-LP03 being having a 0.5 mm ball but writing with a 0.7 mm line diameter, due to how the water-based rollerball ink spreads on paper.
This water-based ink has pigments inside it so that it’s water-resistant and fraud-resistant.
