Most pens take a "Parker style" refill. Some pens take a "Cross Refill" and some take "Roller Ball" refills. If you're not sure which style of refill, or you cannot find the card that came with the pen that tells you what style of refill, please feel free to contact us and we will help the best we can.
You can buy refills at most office supply stores, ie: Staples, Office Depot, Or other similar office stores.
If you have a problem with your pen, please fill free to contact us! We will be glad to help.
