TWSBI ECO Transparent Yellow Fountain PenTWSBI fountain pens are beloved for their clear barrels (sometimes called demonstrators) that allow users to see the ink inside. The pen has an interior ink filling piston system that holds much more ink than a typical fountain pen cartridge. It also allows you to fill your pen up with ink without the use of a converter. Just unscrew the cap at the end of the pen, dip the pen into ink, fill, and screw the cap back on. The TWSBI ECO (for "Economical")

Good quality, although expensive
Size: 1 Count (Pack of 1), Style: Cartridge Ink
Frankly, as with other printers, I thought that I could use reconditioned cartridges with this printer. The first set I purchased was not recognized, thus I have had to purchase genuine products. The cartridges, also offering good color, do not last long. It's a trade-off between cost and quality.
