I’ve been asked quite a few times about swatches I use in my notes and in my journal. As you can see my favorite is probably the grey Mildliner 😂 I use my Muji gel ink pen in 0.38 with all of these. Pictured: Zebra Mildliners. Stabilo point 88 pens. Staedtler Triplus Fineliner nature pack. My new Pentel brush pen.
PS - sorry the lines aren’t very straight, I have a hard time drawing straight lines on unlined paper 😂
