My first impression was that it was very well made. My first effort was a simple graphite sketch of 2 apples. Although very smooth the surface had enough tooth to lay down a reasonable amount of graphite. I found blending quite easy and I had no trouble lifting unwanted graphite from the paper with a putty eraser.
My second attempt was with coloured pencils. In this case I chose the most difficult CPs that I had, "Spectrum Noir".
The CPs were a bit difficult to work but it gave favourable results. The CP was a bit more difficult to layer but just needed a bit more elbow grease. The colours looked a bit weak but I'm inclined to think that was the CP and not the paper.
In all I think this paper is really good for sketching and doodling. My only reservation would be in using wet media including fixatives as I don't think the paper is thick enough to handle the wet without serious cockling. Great for graphite though.
