When I need more permanent notes, I use this other $13 ereasable notebook: "2019 Elfinbook Smart Reusable Erasable Spiral A5 Notebook Paper Notepad Pocketbook Diary Journal Office School Drawing Gift 4.8". https://www.aliexpress.com/item/32859074901.html?spm=a2g0s.9...

As for the previous one (single page scribble) then I found in the past that I usually have a new single page each day on my desk for tasks minor notes of that page and it's now replacing it - this is its main usage.
