Cartridges come in a handful of colors. Ink bottles come in hundreds of colors. The converter is the bridge between them.

Here’s how it works

You insert the converter into the INK in place of a cartridge, dip the nib into the ink bottle, and turn the black knob. The piston moves backward and draws the ink into the chamber. It holds 0.5 ml, which—depending on the nib width—is enough for several pages or even several days.

Why do I need the ink converter for the INK fountain pen?

The ink converter lets you fill the INK fountain pen with your own ink from an inkwell—instead of relying on cartridges. This is more sustainable and gives you the freedom to choose any color.

How does the piston mechanism work?

Simply dip the tip of the fountain pen into the inkwell and turn the piston—the ink is drawn in automatically. No fiddling with cartridges or syringes.

Is the ink converter compatible with all INK models?

Yes, the ink converter fits both the INK fountain pens in aluminum (Aurora Green, Night Sky, Warp Black) and the titanium versions (Matte, DLC).

Can the ink converter be used with the TILT inkwell?

Yes, it's perfect, actually. The ink converter and the TILT inkwell from Stilform are designed to work together as a system—the TILT's tilting design makes it easy to fill the inkwell right down to the last drop.
