I would instead recommend Pilot G-2 0.5mm roller ball gel pens, or if for some reason you don't like Pilot pens, Foray gel pens are also nice.

-- Ink remains fast- Pilot G2-07 -- Ink remains

I've generally had good experiences with Zebra gel pens in the past, and even with this very product in the past--the flow is not as generous as the Pilot gel pens, so they tend to smear less.

Every bit as good as a Pilot G-2 at a fraction of a price!!Can't even tell the difference
