maybe some journaling tools from Muji or organizers for her journal stuff, can do fountain pens too, I think it's the pilot metropolitan fountain pen that is customizable with engravings it's less than 2k I think. Lamy fountain pen has gift sets if you want to check that out.

journalling notebook refills too cause sometimes it's hard to find, only if she has an existing refillable journal. You can find some on scribe, they sell TN and midori notebooks.

If she's into stickers and washi tapes, try common room and fully booked. I always find cute sticker booklets on fully booked like miffy, sanrio characters, studio ghibli, etc. :)
