I like the thin sharpies and Bic permanent ink pens so I can have ink colors to match. There is also a very think sharpie pen. Not a ball point, but a felt tip (I think that's what it's called) that is nice. I've often wondered if a regular ball point pen would be acceptable. I hate my handwriting and would love to be able to print my journaling on the laptop.
That's why I choose a "hand writing" font. I always seem to get the pen everybody tries out at the store, that somehow gets put back in the hermetically sealed container. Then it runs out of ink mid way in the 3rd letter.
I have been using the .05 one in black. I like Sakura quality as they make so many other products from ink pads to gel pens to these regular writing pens. Mainly a company that sticks to one type of product, ink.
of course, if you have Don's kind of luck I don't know what to recommend! 😀
