Thank you for viewing! This is a sketchbook that was used in school art class. It appears that only the first page was used. There are 9 thick pages in the first half. There are 10 thin pages in the second half. It's a product that sells for 1250 yen on Amazon. I hope someone who will use it will buy it. The cover has a name written on it, so it will be shipped with the name blacked out.
