does this pen come with anything bolder than 1.0?

Hi Irv! 1.0 MM is the largest size we have in this version of Jetstream. Thank You! uni-ball Team

Do they smear/smudge when you use highlighters over them?

This is my favorite all time pen. I have been using these pens for 10+ years now. It does not smear/smudge when highlighting over.

Are these oil-based inks?

Theses are ballpoint pens so the ink is oil based. Rollerball pens are water based.
