What should I get my 16 year old friend for her birthday?

So my friend’s 16th birthday is coming up soon and I need ideas about what to get her OR make for her. We used to date for about a year and in that time I bought her a necklace and a bunch of drawing stuff (she’s really into drawing). For a while I thought about sewing her a kimono (She likes anime and Japanese culture) but quickly realized my sewing skills were lacking. I realize this is a hard question to answer because you don’t know her, but I’m just really out of ideas, any help?
