Hi, I have few questions for you.
A converter is what allows a fountain pen to use a bottled ink. Right?
My Parker Sonnet came with a slide converter with a ball inside. But I saw other kinds of converters in YouTube.
What is the difference between a twist and a slide converter?
What are pros and cons of each?
Which one do you prefer for my Sonnet?
Thank you very much in advance.
