Rite In The Rain Weatherproof Laser Printer Paper, A4 Paper Size 21 x 29.7cm, 20# White, 200 Sheet Pack (No. 8512)

Aeration of the paper is very very very important. Take the paper and flip through the pages a few times flip it over and flip through it some more and you’re ready to print.

I'm attaching a photo of the back of the box which discusses what to write with for best results. Writing instruments that won't work are gel pens, most highlighters, fountain pens, water colors, and acrylic paint. What works well is all pencils, rite in the rain pens, wax markers, crayons, oil pastels and oil paint when wet or dry. Permanent markers and standard ballpoints work well but only when dry. This is fun and handy!

I love this paper! I keep a rain log, and this is great. I print a grid on it with dates and rain amounts, and since it's waterproof, I can take it on a clipboard right to the rain gauge.

Bought this for field work, very good. I usually write with pencil.
