I have bought local snacks like salted egg, fish skin, and bak kwa is quite a hit with foreign colleagues, especially from China! For Germans, good-quality tea or coffee from local brands can be a nice touch too. Risis gifts are great for something more premium.
I also give our foreign visitors a customized water bottle with a touching quote: ‘Remember, no matter where you are in the world, you’ll always have a home here with us.’ I order them from [bottledevents.com](link url) and they make such a thoughtful gift. Plus, when they use it during their flight, it’s a little reminder of their time with us!
