Wow, thank you so much! And the sketchbook is a basic A4 size, with a black hardcover. I really like it but it's a little bit too big to bring with me all the time (and kind of hard to draw in it without getting noticed by a teacher)
I know what you mean! A lot of teachers don't let me draw at school either. So I bought a pocket sized notebook with blank pages and teachers rarely notice it! Unfortunately the quality of the paper is not that great (because it's meant for writing) so I wish I had bought a pocket sized sketchbook instead of a notebook.. But that won't be a problem if you get a pocket moleskine sketchbook
