Uniball Jetstream 0.5 Review


The Uniball Jetstream is usually the pen that is recommended to people when starting to look for a pen that’s ‘a little bit nicer’. There is good reason for this but in today’s post I thought I would dig into this pen a little more and give my thoughts.

Benefits of the Jetstream.

The Jetstream is an entry level pen, one that you could use everyday but you won’t cry if you lose or misplace it. The Jetstream is a rollerball with its big selling point being an ‘ultra-quick-drying hybrid gel ink’. To add to this the ink is waterproof and fade-proof. Essentially in this one entry level pen you’re getting a lot more than a standard pen which makes it incredibly versatile and a great recommendation to a budding pen addict.


The Pen itself.

I bought my Jetstream from an actual shop, shocking I know, so I think I have the Sport version. It’s a lovely pastel purple colour with white accents. There is a clip, which I never use, and a nice soft grip section. Sometimes these can be overly padded and get in the way but the Jetstreams grip section is comfortable making it easy to use for long periods of writing time.


Writing with the Jetstream.

I am not an everyday user of the Jetstream despite it’s many benefits. There are so many pens to use that the Jetstream rarely gets a look in. Mine has a 0.5mm refill which gives a very thin line, which looks much thinner than the 0.5 advertised. The ink is smooth and works really well on your nicer paper, such as the MD Paper in my writing sample below, but also standard printer paper.


Overall thoughts.

I am a fan of Uniball pens as a whole. They always write well and feel good to use, the ink is smooth and dark and rarely skips or gives any glooping issues. The Jetstream is no different. It’s a great pen to have in your arsenal and despite my sporadic use it always works first time.

Sometimes it’s not about the expensive or finding the new thing to enjoy stationery or writing tools. Using the simple can be refreshing and enjoyable.


Baron Fig Mysterium Review


Baron Fig sent me their latest limited edition Squire, Mysterium, to test and review here on the blog. All the thoughts and opinions shared here are my own.

The latest limited edition Baron Fig Squire is theMysterium, a vibrant and bright orange pen, always a popular choice.


The Mysterium comes with a short story written by Harry Marks which can be found here. I was half expecting to receive a physical copy of this story with my pen but unfortunately not, this lives online only. The pen and story focuses on a space theme and what lies beyond our planet. The Mysterium sees a return to the aluminium pen body after a few trials with other materials and does so in style with a bright orange body and a geometric logo etched in white on one side.


The orange body does present some small issues. If you really examine this up closely you can see some of the machined lines on the body. The Clicky Posthighlighted this in his post, so head over there for the full details, but the colour makes this all a little more visible. To be clear you really have to look closely at the pen.


I have also found that with the lightweight body the refill does skip a little. This could definitely be a dodgy refill and nothing to do with the pen, however I noticed a similar issue with The Insightful Spectre limited edition that didn’t arise with the brass Key limited edition.


Despite these small things I really like this limited edition. The colour is great and the Squire continues to be one of my go to rollerball pens and the pen I use the most when on the move. Honestly I am a little surprised that this limited edition is still available, I thought this would sell out super quick like the Experiment. So as it’s available I suggest you head on over and grab one of these pens while you can.


Thanks for the guys at Baron Fig for sending me the Mysterium Squire to review here on The Finer Point.

A mass of Uni-ball pens

Last month Uni-ball offered to send me a selection of their products to review on the blog. I have been using a few of these pens over the past few weeks to test out how they work in my everyday writing. The opinions expressed in this review are my own and aren’t influenced by Uni-ball in any way.

Uni-ball Air

Part of the Uni-ball package were two Uni-ball Air pens. I wasn’t familiar with these pens before testing them out for this review. The first thing I noticed was how the grip section through to the tip of the pen merged into one. It’s very distinctive and looks a little futuristic. It does make it hard to see where the tip is and took some getting used.

The grip section on the Air isn’t particularly comfortable. It’s completely smooth made from a high gloss plastic material which isn’t grip friendly.

I received both pens with a broad tip. There isn’t a specific size call out but it’s definitely edging towards the 1mm tip size. The ink performs well on a variety of different paper stocks, although on the Mnemosyne paper I did notice a bit of feathering. The ink flows as you would expect from a rollerball pen and the colours are deep and vibrant which is good.

I don’t think the Air would be a pen I would buy. In Uni-balls current line-up I don’t really see the appeal, I think there are other rollerballs that work better and have better tip sizes, such as the Vision Elite.

Uni-ball Signo TSI

The Signo TSI is Uni-balls version of the Pilot Frixon erasable pen. I didn’t actually realise this when I started using the pen, but after a while the rubber like end of the pen intrigued me enough to test if this was an eraser.

Again the grip section on this pen is a smooth matte plastic material with an attempt at ridges cut in to give grip but they’re pretty useless. The ink is ok, a little patchy and I am not sure if that’s the ink colour I have or the ink make-up of the pen.

Erasable pens may have a purpose and of use to some people but it’s not something I need or enjoy using. I think there is a big sacrifice in the performance of the ink which I prefer not to take.


I have reviewed the Uni-pin drawing pens on the blog before therefore I won’t regurgitate old opinions. I did receive a few of these pens including a blue and red version which I hadn’t tried before. I have been using these pens in my bullet journal for marking off tasks and adding colour accents to my headers. For drawing pens I like using black ink and always have a use for these but less so on the coloured ink pens.

I do enjoy the Uni Pin drawing pens a lot and think they are one of my favourites. The price is great and they write really well therefore I would always recommend these pens.

Overall thoughts

This Uni-ball pen pack didn’t really showcase the best of what Uni-ball has to offer. I have used a few of their products in the past and I have always liked the Uni-ball rollerball pens. The Air and the Signo TSI feel weak in comparison to other pens within their line-up and there just isn’t enough pull to make me want to buy and use these pens.

Thank you Uni-ball for sending me this selection of pens to test. All views expressed in this review are my own.

Kuretake Zig Cocoiro Rollerball Pen Review

The Kuretake Zig Cocoiro Rollerball Pen first caught my eye when I was watching a YouTube video. I was intrigued by the unusual barrel design and decided I need to try one out for myself.

Pick the right style for you

The Kuretake Zig Cocoiro pen is a pen with options, you get to choose from several pretty, colourful barrels and then pick your refill. I bought two of the barrels, one seashell pink and one duck egg blue. I then picked up a 0.3mm black rollerball refill and a letter pen refill in mint green. I haven’t really used the letter pen refill yet, but I have been using the rollerball on a daily basis therefore this review will focus on the rollerball only.

Unique barrel design

As I said the initial attraction for me was the unusual shape of the pen barrel and the gorgeous colours. When using it, it fits really nicely in your hand with the subtle curves of barrel making it very comfortable to hold. It can also be used comfortably posted and unposted without any issues.

I was surprised by the light weight of the pen. This is a plastic pen therefore I wouldn’t really expect too much weight, but for extended periods of time writing the Zig Cocoiro is really very comfortable to use.

The refill

The black refill of the rollerball refill gives you a very dark, solid black line. It reminds me in some ways of my Uni-ball Eye Needlepoint pen. With rollerball pens generally I have found you get a smooth writing experience and I have never had any issues with skipping. The Kuretake Zig Cocoiro is no different.

Due to the properties of rollerball ink you can use this pen with almost any paper stock. It works well with my Field Notes memo books although with the standard 50lb or 60lb paper stock you do get a bit of ghosting. This doesn’t bother me too much but it is worth bearing in mind.

Overall thoughts

Overall I really like the Kuretake Zig Cocoiro Rollerball pen. It reminds me of the Uni-ball rollerball pens such as the Eye and Vision Elite. As a go to pen and for using on the go I think this is a solid choice.

The winning points with the Cocoiro are the fun colour barrel options, the fact that it is comfortable to hold and light to carry. I also like the fact I can easily replace the refills once they are used out rather thank buying a whole new pen each time. The only small downside I can think of is that it appears to be difficult to get different rollerball refill colours here in the UK, but that is me being extremely fussy.
