Review: The Ultimate Pen. - An amazing pen which saves you from having to hold 4 different pens & a pencil/eraser. Smooth, convenient, worth it Ideal for Note Taking at Work/School. Very comfortable to hold, writing feels good and design looks seamless
Review: Worth every penny and much more! - I bought this along with the "Uni-Ball Clipturn 3 in 1" and the "Uni-ball Signo Premier Rollerball" which are both estimated to arrive before this pen and I've used this pen for about 2 hours, normally given the extensive speed and amount I write my assignments with I just use my laptop to type them up; nope- not this time. I wanted to test the comfort and ink-flow of this pen, I had used a Uni Jetstream before and this lasted me around 2 1/2 years which is pretty good given I was doing 3 sciences, english lit and language and art (Yes, I used it to draw). This pen is a straight upgrade from the essentially stock-no frills one. The nicely integrated pencil is easy to access and no, it doesn't activate accidently as one may think and the writing, oh it's a pleasure to use, I found myself looking for more information just so I could use this amazing product, and does it have a nice rubber grip? Hell yes! The different pen switches have a sleek look with a line on them indicating the colour of the pen correspondent with that switch, it looks fancy- and although plastic, it feels durable and firm. I would recommend this to anyone, keep this up Uni.

## Questions & Answers

**Q: Is this pen metal or plastic?**
A: the bottom of the pen including inside of the rubber sleeve is metal, and the top part of the pen is plastic. So the bottom to about 3 times heavier then the top of the pen.

**Q: How do you refill the lead?  I tried the way they said in one of the reviews and it didn't work.  If pull off the end of the pen, please say which**
A: I just checked my pen and here's how you add pencil lead: Unscrew and remove the front of the pen (the grip section). Look closely at the pencil part's metal sleeve and you'll see that about 1/2″ down from the pen body, there's a spot where the lower part of the metal pencil sleeve slides over the upper part. Pull the bottom part of the metal pencil sleeve off. Add lead to the upper part of the metal sleeve, then replace the lower part by slipping it back into place. Hope this helps!!

**Q: Can I use gel ink refills instead of the regular ink refills? And how fine is the tip? Can that be changed by utilizing different size refills?**
A: The tip is .7mm. Unit makes this pen with all types of different tip sizes, but I don't know about gel refills. The refills for the Signo multi may work, but I have not had a chance to try them yet. I don't want to waste 6 bucks on the experiment. Jet Pens carries a much larger line up of pens. Prices and availability are odd on Amazon because these pens are made for the Japanese market and not too many companies import them. https://www.jetpens.com/Uni-Jetstream-Multi-Pens/ct/858

**Q: Is the Barrel solid black? Is there a silver logo  halfway through the pen? The one on the youtube reviews look different from the picture**
A: My pen is solid black at the rubber grip and the barrel. There is a silver ring between them as shown in the picture. There is no logo on the barrel, but it says uni JETSTREAM on the clip.
