This is a type of chocolate.
From the manufacturer:
Welcome to the world of "Meiji The Chocolate," the world in which taste sensations are born from "Bean to Bar" -- a process by which cocoa beans are carefully selected in order to create the perfect bar of chocolate. Each bar reflects an elegant luster, emits a sweet fragrance, and melts heavenly in your mouth.
This Elegant Bitter variety mainly uses cocoa beans from the Tome-Acu region of Brazil. A fruity and elegant aroma is brought out with a low-temperature, light roast.
Contains 70% cacao.
