Ecchi sketchy sketchbook.jpg
Thank you for your hard work at Reitaisai! I've granted the honor to make this official Reitaisai sketchbook! It seems that it sold out completely, thank you everyone who bought it, and sorry for everyone who wanted to buy it but couldn't! P.S. 5/30: Just read this on the official site: "A cute sketchbook design, featuring Flan and Koishi furiously making sketches of their sisters on its cover", that made me ROTFL!
