Gift ideas for my cousin?

Hello! I'm going on a trip this summer back to Taiwan to visit my relatives. I was wondering if anyone had ideas for gifts to bring for my cousin? We're around the same age (late teens). I live near a couple malls with trendy stores and I can order things online since I have a couple months. She's not too interested in beauty products and dresses pretty minimalist, but she loves collecting cute trinkets and keychains from like Sanrio and chibi anime merch. Since she's from Taiwan and takes lots of trips to Japan and China usually, she has a pretty big collection and she's always gifting me cute things of my favorite characters. I was wondering if there's anything unique from America that you guys think she'd like?
