Sherpa Fountain Pen

I like my Sherpas and I use the heck out of my dog and cat pens. Now I find out that the Sherpa makes their own fountain pen insert. I have spent some time with this one and it works great. As you can see the Sherpa comes with a Sharpie and a Sherpa roller ball insert.

 Here is a better picture of the fountain pen. Add one to your Sherpa collection.
