Knitting with mink & mink thread?

I received as a gift 6 mink skiens with 6 thread spools to match.
I am not sure if I am suppose to knit this together. Also if weight is 50g. Suggested Needle Size: 2.5mm-3.5mm. How many yards would that be approx? Is this a fingering yarn or if I add thread does it become thicker?
See picture

Sounds like interesting yarn.

It’s knit on a ~US1 or 2 up to a US4 needle so that would make it a fingering yarn. You’d have to try it out and see what gauge you get with and without the addition of the thread.
At about 4.4yds per gram, 50 gms is ~220yds
