Private Reserve contacted me, and asked if I’d like to try some inks. The Infinity Inks series has intrigued me since it was first released in 2021, and I chose a couple to try. Inks in the Infinity series are made using an E.C.O. (Extended Cap Off) formula, which is supposed to allow you to keep the cap off for extended periods of time without drying out the ink. According to the claims, no more worrying about capping and recapping as you pause while you write. I tested this ink extensively, and it really works!

This is Private Reserve Infinity Turquoise. It’s a bright, bold turquoise blue with a bit of color variation on some papers. It’s not the strongest shading ink, but there is some variety. As you can see under the ink splat, you can also get some edge darkening on the stroke profile, but this is heavily dependent on the paper style and nib you choose. It’s a very attractive blue. The color is difficult to photograph, and I’d say it is actually lighter and brighter than I’ve been able to show in some of my images. The color has a fun personality.

I routinely wrote without recapping my pens, and I have to say, I’m impressed! I don’t know what they’ve done, but it definitely works. I even left the pen uncapped on my desk and stepped out for dinner. An hour later, the pen immediately started writing, as if I’d never put it down. This may be the solution for pens that suffer from hard starts.

Infinity Turquoise is slightly on the dry side, but it flows very comfortably. I expected that the E.C.O. formula would make it a wet ink, but on the page, I’d call it a neutral to slightly dry. It’s hard to categorize the feel, but I wouldn’t worry about it feeling too dry in this case. It’s a comfortable writing experience.

I did notice that every once in a while, the first stroke or two after resuming would be darker than the ones that followed. The ink was not starting to dry out, as it was as likely to happen after just a minute or two pause, as it was after a thirty-minute pause, and in my experience, it remains wet in the nib and feed for much longer than that. (I actually liked the dark first stroke effect, and kind of hoped it would happen more often!)

In writing performance, Infinity Turquoise is a pretty good writing ink. I used a Jowo medium nib for most of my testing. Strokes were fairly clean. There’s a bit of minor spread on some papers, but I didn’t find any real feathering. Surprisingly, once it hits the page, drying was very fast in most cases, and never longer than average on any of the paper styles that I tried.

Turquoise is one of six colors in the Infinity Ink series. You can find them in 60 ml bottles for US$20-$25 at many popular retailers. Private Reserve’s E.C.O. formula is an interesting innovation. It really does solve a problem that can ruin the writing experience of a troublesome pen. Constantly capping your pen is an ingrained habit for many of us, but it’s a real pressure to be free of the need!
