Speaking of the refill, Caran d'Ache uses their own proprietary refill for these pens — the Caran d'Ache Goliath. It's roughly the same size as a standard Parker-style refill, but it uses a proprietary ink formula. The ink is actually really good, and it's come to be one of my favorites. It always has a little trouble with cold starts after being stored for more than a day, but once it starts writing after a couple of squiggle lines, it's smooth, dark, and consistent. It's one of those dependable refills that never lets you down, and I love it for that. You can swap in a standard Parker-style refill in this pen even though the refills aren't the same length. The Parker ballpoint tip protrudes an extra millimeter or two in this pen, but you could either ignore it, or trim it down fairly easily. This is an easy way to use different types and colors of inks in this pen since Caran d'Ache only offers Fine, Medium, and Bold styles of Black, Blue, Red, and Green ink in their Goliath line.
The Caran d'Ache 849 by Cult Pens is a fantastic ballpoint pen for any occasion. It's a super dependable pen at a great price, and you really can't beat the unique aesthetic the 849 offers.
