50ml bottle of permanent and waterproof pigment ink.
Pigment inks should not be left in pens for prolonged periods of time between use as they can clog feeds. If your pen is to be left unused for a period of time, ensure it is emptied and flushed through with clean water.
The bottle contains a novel reservoir design which allows you to use every last drop of the ink. Turn the bottle upside down before filling and the reservoir is topped up, then insert your pen and fill as normal.
Colors: Kiwa-Guro / Seiboku / Souboku
Please note: Sailor are redesigning their products, so the bottle and packaging may vary from the image above.
