I bought dozens of fountain pens in 2018. It's enough now. I came to the conclusion that I don't need any more. I have only few chances to write something at all. Almost anything I do is writing for the writing purpose and not for the need.
However I greatly improved my handwriting. And that's why I will continue writing with fountain pens. But I don't need another one. No matter if it's $1 or $800. They only do write. And I don't have something I have to write with it.
