TRAVELER's Company Brass Rollerball Pen

Super well made and I’m glad I can use my fountain pen ink in it.

One of the things I love best about this pen is that it uses fountain pen ink cartridges for refills, which opens up so many possibilities for writing with different colored inks. I've only had the pen a short time--long enough to go through half of a cartridge--so I can't speak to its wear or longevity, but so far it writes really smoothly. The only drawback I've come across so far is that it puts down a lot of ink on the page. It's advertised as having a 0.5 mm rollerball tip, but the ink on the page seems much thicker than most 0.5 mm pens I own. I'm still glad I got the pen but my preference for writing in my Traveler's Company inserts is the raw brass Fisher's space pen (https://yosekastationery.mom/products/fisher-space-pen-raw?_pos=1&_sid=4e507c878&_ss=r) with a 0.5 mm refill, which looks very similar to this pen and looks beautiful with the leather notebooks.
