Acoustic Guitar Strings

[jcollin]

I'm checking out Gibson Acoustic Guitar Strings SAG-BRS10, Masterbuilt Premium 80/20 Brass .010-.047

at furtados [1] in India. Are these genuine Gibson strings? Because I don't find them at https://www.gibson.com/en-US/Gear/Acoustic-Strings, which is suspicious to me. Why they are not shown in gibson.com?
