I bought each of my players a notebook for Xmas this year because none of them takes notes. I limited myself to under $20 per player. One has actually started taking notes because of it. He's even gone as far as to draw a map of the sword coast in it from the reference material I gave them.
I went with leather notebooks from Amazon that used either A5 or A6 size journal paper and binder rings, so that they can reuse it on future campaigns if they'd like.
Here are a few examples of the ones I picked out: College of Spirits Bard: https://a.co/d/2cNSrAc
Moon Druid: https://a.co/d/hybivRL
