Cotsman Watercolor Paper, Medium (N.P. surface) 230g, F0 size, 18 sheets. I am selling this to declutter. Although it is unused, it has been stored for a long time, so the watercolor paper has deteriorated (yellowing, etc.). Upon inspection, all 18 sheets had small spots like those in the photos. Please check the photos and consider purchasing if you are okay with this. Shipping will be done by waterproofing with a clear bag, etc., and then sent via Yu-Packet Post. #Sketchbook
