putty rubber that I've been meaning to get for months.
I saw a very useful sketch book and now I'm kicking myself that I didn't pick one up. They were piled up near the entrance with a reduced sign above them. They were in various sizes from A3 to pocket size, spiral bound with plain hard board covers containing four types of paper, ten sheets of each type. Smooth cartridge, smooth watercolor, rough watercolor and oil canvas textured paper, brilliant!
