Our G2 Refill adapter converts your pen to a rollerball by simply threading this into the section in place of a Jowo #6 nib unit. This adapter was designed to work in all of the Jowo#6 cartridge/converter pens made by Little Hollow Customs.
Compatible with any pen designed for a Jowo #6 nib unit and international size cartridge/converter, but may need a spacer for pens from other makers depending on the internal length of the pen. Ideal internal length is 95mm from the front of the section to the bottom of the body internals.
Designed for a Pilot G2 refill (111.1mm length), and may work with other rollerball refills depending on length.
