Returning to Tokyo, and hoping to bring some cheap but trendy souvenirs for my friends

I'm leaving the US soon (living in Tokyo) and like the title says, I want to bring some souvenirs. A few years ago Trader Joe's bags were super "in" for some reason? Is that still a thing? What's the latest new trend that I could shove 15 of into a suitcase without taking up too much space or money?

I appreciate any advice on this! My friends are mostly 30-40 year old women fwiw.
