Those Parkers and Watermans are probably really cool pens! I really need to get around to getting a vintage flex pen, but I’m just not a pen buyer, I’m an ink buyer ;D five bottles is nothing, lol, I’ve got a shelf of inks.
I use a Lamy Al-Star as my everyday driver, I need to get a fine or extra fine nib for it, this medium is actually too fat for my handwriting, but it works for now, I just write a bit larger than I would like.
