Collection: Fountain Pen Refills for Conklin

Easy Decision, Try Them All

Conklin fountain pens can be refilled with standard international-sized ink cartridges or with the ink converter originally provided with the pen and any brand of bottled ink.

Colorado Pen offers international-sized ink cartridges in over thirty different colors. This specially formulated ink helps keep your Conklin fountain pen writing smoothly. 

If you still have your original ink converter, Colorado Pen has a large selection of bottled ink from which to choose. Our brand arrives in a huge 90ml bottle. New converters are also available. Or take a look at the variety of ink types and colors under the Private Reserve brand.
