Gifts fir kids from other countries?

Hey yall I’m going to Europe in the fall mostly in Germany, but also just wandering around to surrounding countries (no real itinerary) for a month this year! I have a few nieces and nephews 18-12 and I want to get them some souvenirs while I’m away! What have you gotten your kids/teens in your family from other places?

I will try to look for things more centered towards their personalities, but trying to think of general ideas ahead of time, thank you!😊
