Product description

Rollerball refill, ball diameter 0.5 mm (equiv. to a line-width of approx. 0.3 mm), colour: blue

With the ink roller refills, all Tombow ink rollers become a long-term companion. Depending on personal preference, the rollerballs can be refilled in three different ball diameters and three different colors (blue, red, black). The high-quality pigment ink is additionally protected against drying out by a plastic ball. This must be removed before the first use.
