Probably my go-to G2 style refill for a medium ballpoint. Have tried many many others.
Found refills needed for a specific pen. The delivery was quick. Got a note from someone at the company personally thanking me for my purchase. Pretty awesome:
My brother often sends me old school pens like the Retro 51. I have been sorting through supplies and losing what I am not using. Many beautiful pens needed refills. When I found Pen Place and they sent needed cartridges so fast I felt a renaissance of writing coming back. First letter was to thank my brother. The satisfaction of handwriting a letter came flooding back to me. ( SOH Paul Ryan doesn't know what's hit him.)
