"Behavioral Economics is the Strongest Academic Discipline" Namika Sagara Price: ¥1700 Purchased this spring at a bookstore in Chiba Prefecture. It was a beautiful item, never read, but I spilled green tea on it... (See photo) It was green tea, and I wiped it up and dried it immediately, so there is no smell. It's yellowed, but it's in a condition that doesn't interfere with reading. Since it's unread, there are no markings. If you don't mind, please consider purchasing. Please note that we cannot accept any complaints or returns after purchase.
