I received this as a bonus when I bought a computer at PC Koubou, but I don't plan to use it, so I'm giving it away. The size is A2, and I think it's large and easy to use. I hope it goes to someone who likes it (o^^o) I took it home carefully to avoid scratches and creases as much as possible. I will ship it rolled up in a poster-sized cardboard tube, with a vinyl sheet on the outside to protect it from getting wet.
