Lightweight 5mm dot grid?

I just got my first pocket binder yesterday and I absolutely love it but why no 5mm dot grid option for the lightweight paper 😭

3.5mm is too small for most things, 7.5mm is fine I guess but I'd rather smaller, and I don't like full grid (might have to end up dealing with it though).

Anyone know of any alternative paper options? I might even end up making my own refills TBH. I've already got a hole punch; maybe I'll need to get a paper cutter as well.
