Ballpoint refills

Did you know that 90% of all ballpoint pens use the widely accepted ‘Parker Style’ refill body shape? Almost every brand accepted this as the ‘ballpoint standard’ about fifty years ago. 

Forget your pen’s brand -if a Parker Style ballpoint refill is what fits your pen, then you can choose from three ink technologies; the old standard oil-based ink, GEL ink, or Liquid Ink. This is the ink that a rollerball refill uses which is referred to as ‘liquid’ ink. It is what gives the fluid feel to rollerball refills and is as close to a true fountain pen ink as you will get in a ballpoint shaped refill.

Fountain Pens

Whether you use bottles or cartridges, we have your ink! 

Almost every fountain pen we offer can use bottled ink. Just make sure the pens ships with an ink converter. If not, we’ll have one listed that fits perfectly as an option. 

We have various brands of ink to give you a diverse color choice as well as various formulations. Our best-selling bottled ink is our own in-house developed brand, Colorado Pen. This ink is formulated specifically to our specifications. The primary difference with our own ink is that the base liquid itself has proven properties to enhance flow and to be easier to clean the feed when changing colors or simply cleaning your nib and feed. 

Most all of our customers have tried and converted to the Colorado Pen brand of ink.
