This is a set of 5 Pentel Ain mechanical pencil lead refills (H). It comes with a sticker of Ken Shimura's "Bakadono-sama" (Foolish Lord). It's a collaboration between Ain mechanical pencil lead and "A-in!" (a catchphrase). Brand new, unused. The Bakadono sticker seems to change color with temperature, but as it is an old item, there is no guarantee that the color will change due to aging. We are looking forward to your purchase if you understand this.
