This is a nice paper pad at a very good price. After using it and testing it, I can say it's only good for drawing with coloured pencils and graphite, nothing water-soluble or needing of the slightly amount of water.
I bought this pad due to the price and to the fact that use cheap pads to clean my paint brushes from paint, when I have some acrylic paint left after a painting and then I use the pages as collage paper in my artwork. I also try new water-soluble crayons colours on them. In both cases this paper fails. Even thick acrylics create bumps on the paper back and the paper corners buckle; the same can be said of water-soluble crayons, which barely require any water. If there is some sort of wet area on a page and I close the pad, the pages get stuck and the spot area breaks off badly. Needless to say, the paper is useless for water colour painting or anything requiring of added water or soft body acrylics.
For the rest, this paper is warm white paper, as per my photo, not black. Actually, I bought the pad thinking that it was black paper due to the description info so I was quite disappointed when I received a white paper pad.
I won't buy it again.
