Like Lays, Pepsi, Kit Kats, etc. other countrys have many flavors that others dont have. Only way to get them is import or a place that sells snacks from other countries. It's very, very common.
Aldi grocery stores import most of they foods. I don't shop there anymore but remember way back going there and getting green beans in a can, and it had sticks in it, from Brazil irc. I'm surprised they are permitted to cause it not FDA approved/ inspected
