Is this pen metal or plastic?

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.

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

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!!

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?

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

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

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.
