GAK. Stone Paper Notebook | No Lines Spiral Notebook Waterproof Sheet Aesthetic Journal for Note Taking | Notebooks for Work & Aesthetic School Supplies | Large Size, White (7.2”x10.1”, 50 sheets)

This is awesome stuff, I don't even know how to describe it. If you try to rip it its like ripping plastic but its not, and if you spill on it you can wipe it off without issue or it leaving a stain. It takes my markers, pens, and pencils, gel or otherwise. It doesn't bleed though. It is so cool. I was at work and I wasn't even testing it on purposed but when I took the lid off my coffee it splattered and got on the notebook and it sat there for awhile before I realized where it all went. I took a Kleenex and wiped it right off and it looked brand new like nothing had ever happened.

I purchased this to sketch and I absolutely love it. The paper is very smooth, making the writing and sketching smooth. My son also sketches and after trying my paper he is buying a few for himself. The best part is, it’s waterproof, no one expects spills, but it can happen.

They said water-proof, so I tested it further and went straight to a café latte. I let it sit for maybe half a minute.Wiped it up with a tissue, and I couldn't even tell where I spilled the coffee.Took a picture of the back of the page that I spilled coffee on after I wrote on it. You can see the ink, but not the coffee stain. There was no smudging either when I rubbed my writing.Now that blows my mind.How is it permeable to ink, but not to coffee?? 🤔Sorcery!It is an unlined and undotted notebook, be advised.It was such a pleasure to write on. Very smooth. There were no imperfections for the nib of the pen to trip on.Incredible quality

I'm actually using this as an art journal/sketchbook for inks (alcohol, dye, acrylic, and pigment based) and fluid paints and it works wonderfully- smooth paper with a sheen.
