Sebastien Bailard, of the awesome RepRap (another DIY fabber project you should definitely check out) sent us a message about the Pilot Varsity disposable fountain pens with which I’m currently having a torrid affair. He says they are refillable:
1. Uncap the pen and set the cap aside. Put the fountain pen, nib point up, into a padded vise.
2. Take some pliers and carefully pull out the nib (you may want to pad the pliers with tape or otherwise protect the nib from marring). The nib will pull out, making a sort of “Schtuppf!” uncorking sound.
3. Set the nib aside and use an eyedropper or improvised pipette to refill the pen with your favorite fountain pen ink (I like Platinum brand Carbon Ink). Don’t use India Ink, it probably won’t work.
4. Replace the nib in the pen with the pliers.
