This is one of the regional special editions for Kit Kat, Shinshu Ringo. Shinshu is the old name of the mountainous Nagano prefecture in central Honshu, Japan. Ringo, is just Japanese for Apple.
The taste of this one is very weak though, I was hoping for a stronger apple flavor.
Thanks to Tomo for find.
tastes more pear than apple I thought…..almost like pear drops?
