Categories Product Support Gatsby/WallStreet Click Post author By admin Post date May 12, 2021 This pen accepts a Parker style refill in either ballpoint or gel. Remove the pen tip by unscrewing it from the main body. Remove the refill, being careful of the spring (it will be needed by the new refill.) Replace the ink refill into the main body, then reattach the tip. ← Slim Style Twist Pen → Gatsby/WallStreet Twist
