Need help picking out a gift for a 12yr old 🙇🏽‍♀️

I'm going to Germany to visit my SO side of the family. I've figured out some nice things to bring over with me for almost everyone but I can't seem to think of anything to get his niece. She is 11 or 12 and I really don't know her that well with the language barrier and living so far away. I know she wanted us to bring her those eos round lip gloss things last time so I don't know if that's helpful.. i was thinking about doing something similar but with a different trendy brand. Any suggestions would be great because I have no idea what ladies this age like!!!

Budget: under $25
