Lanier Combo Pack - 2 Pack - Monteverde® Capless Ceramic Gel™ P42 Ink Refill Compatible with Most Parker® Style Ballpoint Pens - Black (Fine Tip 0.6mm)

Great quality, just be aware that it takes a bit longer than gel to dry, more like a fountain pen. Excellent smoothness, though

I've purchased this multiple times, writes great but it runs out quickly. I love the Parker jotter but I just ended up switching to a zebra sarasa grand using pentel energel ink in the end.

Very nice. Ink writes smoothly and is vivid, but it isn't particularly fine. To be fair I was looking for something to replace my Pilot precise V5 RT. This was the suggestion at a pen store. I've sense learned that Monteverde makes this in a needle point.
