At the commemorative ceremony for the 100,000th visitor to the Ibaraki Nature Museum's special exhibition, a child received these. Since there are two, I'd like to give one to someone who will cherish it. These are can badges featuring illustrations designed by the science illustrator "Tsukunosuke" for the special exhibition "Creatures That Lived with Dinosaurs." Approximately 2.5cm in diameter. For those who are interested. *If you're okay with regular mail, I'll offer a discount. Please let me know.
