Waterproof Field Notebook With Dotted Grid Paper, No Bleed Tear Proof and Waterproof Pages, Yellow Cover 3.5 x 5.5 in. - SuperiorMaker (3 Pack) (Yellow)

I have found that pencil is best so far... pens smudging varies. When using a gel pen it does adventually dry but will smear until dry.

Nice notebooks and I *love* the dot pattern. The pages are a little slick for pencil so find a waterproof pen if you're doing shower thinking or whatnot.

Very good for difficult service.

I got these little notebooks to use with my fountain pens and the paper is so absorbent it will not absorb all of the ink. Good news: no bleed through on the back of pages. Bad news: all of the smudges ever.
