Which strings are these?

These came on my Aerodyne when I got it used, so I don’t know what they are but I love the feel and sound.
Yes they are flat wounds and note the different color ball ends. Thanks in advance.

I don't know for sure, but I think they're the most commonly used and commonly available flats and with the blue silks and colored ball ends, they're easily recognizable.
