Most Waterman fountain pens can be refilled with standard international-sized ink cartridges or with a Waterman ink converter and any brand of bottled ink. If you are unsure, feel free to give us a call at 720.259.1601.
Colorado Pen offers Waterman branded ink cartridges in two sizes: the 1-1/2" standard international-sized cartridges and the large Waterman ink cartridges which measure 2-3/4". Both sizes are available in black, blue and blue/black ink colors. Some Waterman fountain pens will only accommodate the Waterman short cartridge.
The Colorado Pen brand of ink offers international-sized ink cartridges in 31 different colors. This specially formulated ink helps keep your Waterman fountain pen writing smoothly.
If you would like to use an ink converter, that is shown below. Then choose a bottle or two of ink from our large selection. Colorado Pen ink arrives in a huge 90ml bottle. Waterman bottled ink is offered in all the favorite colors.
