Product of North or South (Korea)?

Product is manufactured in Seoul Korea so South.

Is this halal and there is no pig or not ??

The package states they are halal, although I am not an expert in such things. They are chicken, not pork. That being said... There are two ways of thinking about these noodles. On one hand, the freeze-dried nuclear holocaust inside this package will purge your entire system of anything unclean for sure. I mean, they'll also probably take your stomach lining with it, but, you know, priorities. On the other hand, while eating these noodles may not be technically against particular religious tenants, you'll experience a small sample of Hell nonetheless. You'll experience pleasure from the great flavor, but punishment will be swift and brutal. You'll probably survive the ordeal, but a recovery period is probably necessary before the next indulgence. Are you permitted to eat these noodles? Well... yes. *Should* you eat these noodles? Err... well... I won't say no because they are delicious, but I won't say yes because I don't want liability concerns if you somehow transform into a fire breathing dragon.

Is this really just 5 individual serving packs for $14? Seems a bit steep.

Yes, it is steep, but shipping cost is around $10 for the 5 pack, so that's why it around $14.

Does anyone know what flavor these are? I'm vegan, but want to try these.

As of December 2020, the current version of these have EGG listed in the ingredients for the "flakes" (sesame seeds, seaweed, and EGG). I'm vegan too and was pretty upset because I ate multiple packs before randomly noticing the new, and frankly unnecessary, ingredient.
