Reddit mentions of Milka Snax Daim

I'm not a German, but I'm an American living in Germany so I might be able to give you some insight on the German snacks that an American might gravitate towards. We do "snack boxes" a few times a year back to friends in the states with stuff we find in Germany and other European countries and they're always a big hit.

First off, if it's not too late, I'd suggest dropping the Ritter Sport and the Haribo Goldbaren. They're both fantastic snacks and I eat more of both than I should, but they are pretty common in the US.

Aside from that, though, excellent choices in your package. You might want to consider adding these though if you have room:

Milka Snax, particularly the Daim variety (http://www.amazon.co.uk/Milka-Daim-Snax-2er-Pack/dp/B005187BOO). It's almost like a chocolate-covered Bugle, if you remember those, with Daim butter almond in it. Fantastic.

NicNac's (http://www.lorenz-snackworld.de/en/node/351). These are, by far, my favorite German snack along with flippies (the "Curly Peanuts" you already have). They're basically peanuts with a crunchy (I'm assuming fried) coating on it. So good, and every American I've ever introduced to them has become instantly hooked.

Milka Löffe-Ei (https://www.milka.de/Produkte/MilkaL%C3%B6ffel-EiHerbstZeit?categoryId=2469). I tend to see these things more seasonally, so they may not be easily available right now, but they're chocolate eggs with vanilla, chocolate, or another kind of filling. They come in 4- packs with little spoons to crack the top of the egg (supposed to be reminiscent of a soft boiled egg, I guess) and then eat out the filling.

Super Dickman -- They're chocolate covered marshmallows. I'm not a big marshmallow fan, but come on, they're named "Super Dickman".

Other Potato Chip Flavors -- Not sure what you have available, but there are a lot of really unusual potato chip flavors here aside from just paprika. Bacon flavor (although I've heard that's becoming common in the states), roasted chicken flavor, thai chili flavor...all kinds.

Hope that helps. Your international snack box concept seems fantastic and I wish you good luck in getting it off the ground!
