I recently bought a set of Parker pens, consisting of a Jotter ballpoint pen, a mechanical pencil, and a Touché II felt tip pen. You can see the cartridge for the felt-tip pen in the photo.
Does anyone make a felt-tip refill that will fit the pen?
I just had to order refills for my Parker ballpoints. Not sold in stores. Google “Colorado pens” & you’ll probably find the site.
Most office supply stores i.e., Staples etc sell refills for Parker pens, your model may or may not be available.
Note that the OP was specifically about finding refills for the Parker felt-tip pen. If you do a Google search for that specifically, you will find other people looking for the same thing and sites saying that Parker has not made such refills in years.
