Uni-ball Style Fit Mystar 3 Color Multi Pen Body Component - Gun Metal Gray

I spotted this pen while recently browsing JetPens. I'm addicted to the Jetstream series and have a bunch of multi-pens and single-ink pens, as well as a customized Hard Lock that accepts the Jetstream multi-pen refills. I experimented with the first line of Style Fit multi-pens and could never shake the feeling that they were somewhat cheap-feeling. I had a lot of customization options, but a plastic pen will usually feel too light in the hand.

I was excited to see a metal-body Jetstream multi-pen, but this pen has one glaring flaw which became obvious when I put the refills in:

You can't see how much ink is left in the refills.

The clear plastic gap in the middle is only partly useful for seeing the remaining ink supply and for seeing which ink you're currently using. You can't tell the ink color in use directly; you have to see the other two ink colors to determine which one you're using. (Other multi-pens have this same problem.)

Despite being made of metal, this pen feels insubstantial. I know there's a certain advantage in a lightweight pen, and this pen is inexpensive so it's not supposed to feel substantial. But I for one wouldn't mind if Uni/Mitsubishi came out with an upscale multi-pen body in the Style Fit series. (My ideal multi-pen would be a Zebra Sharbo X that can accept Jetstream refills.)

I would score this pen higher if there was a broader selection of body colors.
