Kaweco's passion goes just as deep for the smallest of details as it does for the huge difference between their writing instruments and cheap, mass-made products. 

Kaweco G2 rollerball refills are the same size as the classic Parker style rollerball refill, so they will fit all pens that use that refill.

You can also interchange the G2 Ballpoint and rollerball refills to swap your pen from a rollerball into a ballpoint - cool!

1 refill per pack.
