My Little Pony: Friendship is Magic / Equestria Girls - Complete Wave 5 "Rainbow Rocks" from 2016. The figures is are in great condition - Carefully chosen to be the best possible ones for each set. The set contains all instruments available from Rockin' Music Class Set and 7 figures total: Twilight Sparkle, Pinkie Pie, Applejack, Fluttershy, Rarity, Rainbow Dash and Adagio Dazzle. Some can stand better than others, but there are their only flaws. The figures also come with their colorfull stands.
I have dozens of other Equestria Girls figures. I might have the one you are looking for.
