FatOne, 50mm, Empty Pen is an ideal super wide nib marker for filling with premium water-based refill inks. The high quality refillable empty has been designed for optimum flow control, with a pump-valve system allowing for accurate handling and application. The transparent marker casing makes it easy to assess remaining ink levels.
The FatOne was originally developed for graffiti artists who often used the wide nib for signing sprayed artwork.
The mechanics of the FatOne are straight-forward. To fill with a full 45ml RefillOne bottle, simply unscrew the marker top, remove the metal ball completely (as this component is not needed when using the FatOne with Neuland ink), reinsert the valve, screw the top back on, and then simply pump the ink into the nib.
The result is an exceptionally large marker full of rich colour perfect for those working on a larger scale, or to fill in colour more efficiently.
Transparent empty marker with pump-valve system.
