Jaymo Standard Rollerball Refill

• Manufacturer’s website: Jaymo

The Jaymo Standard Rollerball will fit most pens that take a standard ceramic rollerball (RB) refill. It is roughly 1 mm shorter than most of those refills, so it will also fit in Waterman rollerball pens. This refill is available in black or blue ink in a medium line width. Most third party refill makers offer substitutes for this refill.
