Which Isospeed string is this

[Bent]

Just got some sets of strings.

It says Isospeed Professional Soft (1.30 mm and 1.20 mm) on the package.

(Made in Austria)

I wonder if this really is the usual multi. It feels stiffer, like a syn gut.

Anyone have info on this string ?

I have used some of this and it is different.

More crisp and soft.......
