If you write or sign things a lot, get a couple decent pens. Not expensive ones you'd be upset if you lost them, but not sad, free office pens.
I've gotten numerous compliments on my Pilot Precise V5. It's bold, but easy to read, and if anyone borrows it, they'll notice it's smooth and feels nice to use.
The Precise is a rollerball. If you need a ballpoint, Uni Jetstream is great. Pentel Energel or Bic Inkjoys for gel. Grab a pair of each and you can write on near anything.
Zebra Sarasa Grand is a nice metal body with binder clip type clip if you want an upgrade. The above pens all use the same size refill, so if you like one body but a different ink, you can swap them.
The Grand is around $10, the rest you can find for around $5 for a pair.
If you're using a pen all day, it's an upgrade you'll notice whenever you grab a freebie pen and it's scratchy, the ink skips, and it smudges. It's a nice upgrade that will feel more luxurious than the price would imply.
