About Local soda or cordial from South Korea

I would put Local soda or cordial from South Korea on the list for South Korea because it is the kind of thing that feels useful once you are home, not just another airport purchase. For drinks, I would bring a can or bottle for curiosity rather than fill a suitcase with it. The reason it works is that it gives you a quick reminder of the trip without needing to keep a fragile ornament safe forever.
