Gifts for beginning artist

I'm not an artist (my schtick is fiction writing - can't even draw stick figures straight), but my twin sister is. She's been doing it for a while, but she's still learning. She draws, does art journaling, and has also done digital art in the past (back when artificial intelligence didn't exist).

We have a birthday coming up, and I'd like to get her a gift (that's mailable, as she lives in another state) that is art-related. But I have no idea what to get her. She doesn't share much about her art, and if I started to ask questions, she would probably shut down, and I get it - we were both shamed for being creative by toxic parents growing up, so it's not easy for either of us to share anything about our work. That's why I want to get her an art-related gift to support and encourage her.

Any thoughts? So far, all I can come up with is an art journal.
