The variety of oysters is usually marked by the breeding place of oysters. Ginaton oysters come from the family brand that cultivated them, and the brand logo is often the guarantee of their quality. The word "G" is engraved on the shell of each Jinnado oyster as the logo of Jinnado oyster. In addition to the "G" seal on the oyster shell, there are packaging boxes and wrapping paper printed with "Gillardeau".
