Hi. Does it fit for Vector rollerball?

If you are talking about a Parker Vector then yes it fits

Where are these refills made?

I believe it is by a company called DOKUMENTAL in Germany.

Why are these refills 4.5 inches long when parker refills are 3.8 inches? see unibene asin b07q2tnnrc.

These refills are rollerball refills. For b07q2tnnrc, they are ballpoint refills.

Is the blue a dark blue or blue/black or a light blue? Thanks.

Hi Wally. That's a difficult question to answer as color is subjective. It is not a dark, blue black color, nor is it light blue like the sky. It is a medium blue, leaning more towards the dark spectrum of color than the light. Not sure how helpful that was. I'd say slightly darker than the cap color.
