Refillable rollerball pen without creating wastes

Question

I am looking to find something like a "sustainable pen". The main idea is to use a rollerball pen (for convenience and ease of use), refillable (to avoid having to throw it away) and avoid using disposable pen refills.

I found some Rollerball pen, refillable with ink that could be use in fountain pens. However, it's not easy to use (the ink stay wet for a little while), so I am pretty sure I will not be able to convert people to use this instead of classic plastic Bic pens.

Is there any way to refill a rollerball pen with a ink that is like "gelly" or any other solution to use a rollerball point and not having to throw away a piece of plastic every time it's empty ?

Answer 1

For a sustainable pen, I'd suggest a fountain pen. There are those with a mechanism wherby they can be refilled directly, or those with a disposable cartridges, which could actually be refilled by a syringe, instead of disposed of. (Take a look at the nature, history and development of the ballpoint pen and the ink used to see why refilling a ballpoint type of cartridge will be rather problematic.)
