The Kaweco Sport Fountain Pen and Ink Roller are handy pocket-size pens that both use short standard universal fountain pen ink cartridges. The Kaweco Sport pen barrel is too short for a regular ink converter, so if you want to switch from ink cartridges to bottled ink how can this be done? We can think of 4 methods of doing this:
1) Refill your empty ink cartridges with a blunt-tip needle bottle. We’ve got some instructions on how to do this in a previous blog post: Refill Fountain Pen Ink Cartridges with a Blunt Tip Needle Bottle. The needle bottle method is the easiest in my opinion and is also my personal favorite.
2) Try a Monteverde Mini Standard Ink Converter. This method works pretty well for using bottled ink, but there are a couple of quirky things that should be mentioned. First of all, the Monteverde Mini Converter does not hold very much ink – in fact it holds less ink than a standard ink cartridge. Secondly, the bottom of the mini converter (near the end that attaches to the pen) may need to be wrapped once or twice with clear tape before you put it in your Kaweco so that it stays securely attached to the pen.
3) Use a Kaweco Squeeze Converter for Sport Series Fountain Pens. If you can get your hands on this Kaweco Squeeze Converter, you’ll find that it only works with newer versions of the Kaweco Sport Fountain Pen. It is NOT compatible with the current version (as of 03-10-15) of the Kaweco Ink Roller or some older models of the Kaweco Sport Fountain Pen. This converter works best when it is filled with a syringe or blunt-tip needle bottle.
4) Convert your Kaweco Sport into an eye-dropper fill pen. We’ve got instructions how to do this here: Pen Modification – Convert into Eyedropper Fill. Of any of the 4 methods of using bottled fountain pen ink that we discuss in this blog post, eye-dropper fill allows for the highest ink capacity. The eye-dropper fill method is only suitable for pens with plastic barrels, such as the Kaweco Sport Ice or Classic. (It is NOT suitable for pens with metal barrels such as the Kaweco AL Sport or pens with small holes anywhere in the barrel.) Before you try an eye-dropper conversion, we recommend reading Eyedropper Fountain Pen Pros and Cons.
