What is your favorite ink pen and why?

My sentimental favorite is my old Montblanc fountain pen that I bought when I got my first long term full time job. Decades later I sat on my purse (long story) and broke it.

Now, I am liking my Staples OptiFlow, black ink, which I'm sure I bought because it fine point and inexpensive.

In my lab days, I loved my Sharpies. In my drawing days, I loved my Rapidographs. In my drafting days, I still liked Rapidographs, but mostly used mechanical pencils.

Pilot Explorer, also from Pentel. It's a reed tip pen.

Montblanc rollerball, medium point, blue ink.

I still have a plastic baggie with all my Montblanc pen parts. They're good about fixing a pen. Back in the day, you sent it to them, and they'd replace a part for $6.00. Times change, but they probably would still replace the plastic parts of my pen and use the still good gold bits.

I've never heard of a reed tip pen?

I've been cleaning, a dastardly occupation. I tossed some stuff, but I still have

a Metropolitan Museum of Art pen (rolls eyes, probably worth nineteen cents, if that) and a The Art Institute of Chicago Pen, very clever. I know I've tossed italy pens, so it goes.

They probably call it something else, now. Neither a nib nor a ball. I don't know how else I might describe it. Writes smoothly though, and without pressure.

Lotta help you are.
