For sale Optima RB Flatwound Strings (Like New) $48

I have a like-new set of Optima RB Flatwound strings for sale. Only the E string has been installed, and it is cut to Fender scale length. The remaining strings are brand new & unopened.

These are the round core, nickel flatwound reproductions of the Maxima RB 4440 strings of yore

I'd like to get $48 for the set, and I will cover shipping in the lower 48 states.
