#OnePenOneDay Uni-Ball Jetstream Color Ink Series Blue Black 0.5mm

Pens like this Uni-Ball Jetstream Color Ink Series Blue Black 0.5mm are a prime reason why I took up the #OnePenOneDay project. This pen had ben lost in the shuffle of pens from my old office at my previous employer. I found a bunch of pens like this in a ziploc in a desk drawer at my house just crying out to be used.

The Color Ink Series Jetstreams are as good as advertised. If you can get past the funky barrel (nearly every other Jetstream barrel I have used is better than this one), then you will find a great writing, uniquely colored ink waiting for you. I love this series, and I hope one day Uni-Ball expands these ink colors into different barrel styles.

By the way, this is the second #OnePenOneDay pen I have found that I don't have a traditional review on. I'll be sure to add it to the list. Here is the light blue review for reference purposes.

#OnePenOneDay Lamy Balloon Roller

The Lamy Balloon Roller is one of those pens that I am desperate to love, but has one little thing that keeps it from being perfect. And by perfect I mean I REALLY like this pen, and despite the fact it is 0.7mm, I use it a lot. From me, that is high praise. But, in the initial review I talked about the ink cartridge skipping, and that has never gone away, even after repeated use.

I took a full 8 1/2" x 11" page of notes with this pen last week, and counted six obvious skips on the page. By skipping, I mean the ink line thins out for a partial or full letter, but no more that that. Six times over a full page is not a large number, but it is noticeable to a pen addict like me.

#OnePenOneDay - EnerGel, Sakura, Kaweco, Zebra

The #OnePenOneDay project keeps rolling on - here are the four latest pens to make it through the day:

Pentel EnerGel Euro Needle 0.35mm Blue -- This pen got heavy use on its selected project day, and it is just as good as ever. I took three full pages of notes with it, and it performed flawlessly. This is one of the best pens going, and may take over as my most recommended pen to those new to micro tip pens. Watch out Uni-Ball Signo DX 0.38mm!

Sakura Pigma Micron 03 Black -- See, I really do have a lot of these laying around. If it hasn't already, this pen needs to be added into the pantheon of all-time great pens. The performance is great, and the barrel is sleek and comfortable. Still a winner after all these years.

Kaweco Sport AL -- This was a risky acquisition seeing as I am not the biggest fountain pen guy on the block, but wow is this a great pen. In retrospect, I would have bought the blue black ink instead of the aubergine, but even after sitting around for weeks unused, the ink flows from the nib immediately.

Zebra Regal Roller NR5 -- I liked this pen a lot when it came out, and I still like it a lot, but when I was running it through the challenge I was longing for a finer tip. That is not a knock on this pen at all - in fact it still compares well to the Pilot V5 needle - but it is not going to make my heavy rotation.
