Interested in using bottled inks and leaving cartridges behind? This converts your kaweco fountain pen from a cartridge only pen and opens you up to a wider varied world of fabulous bottled inks!

Like a syringe, the ink is absorbed. The converter is plugged into the front part. Then the mouthpiece is dipped into the ink glass with its nib and drawn it up. Repeating this increases the filling quantity.

For Kaweco Sport Fountain pens.
