I found my favorite combination of notebook and pen. I really like the paper of the Clairfontaine A5 notebooks. They are cheap and available everywhere here. They paper feel very smooth, not grainy but still give a good friction when writing. Speaking of friction, I love the erasable Frixion pens from pilot. I hardly ever use the eraser but I love the feeling of writing with it. The 'clicker' variant of the pen fits…
It’s been 20 years I’ve used their notebooks.
