It is a refillable rollerball pen that takes standard ink cartridges. It sounds like a nice idea but I was wondering if anyone knows if it is any good?
As others have said, looking in on this site can be an expensive business - only stopped by for some advice on razors but now I'm looking at fancy pens too
Not used the Herbin one but the Kaweco Sport Ink Roller seems to work OK (obvious caveat that it's like a roller ball not a fountain pen to write with)
