What color pen do you write with? Do you have to have a certain kind or will any old pen do?
My favorite pens are the one’s hubby brings home from the fire station. lol They are blue ink and I’m sure they aren’t very expensive. They have the fire dept. logo on them and write like a dream. 
He’ll have them in his pocket when he gets home and I snag them. 
Otherwise I just like the plain old blue papermates.
I am a pen junkie, I have a coffee cup full on the desk, about ten in my purse, another 10 or so in my nightstand in case I need to write something in my sleep, and some more in a box in the kitchen!
I like pretty pens, different colors, highlighters, sharpies, sharpie minis, anything that writes!
