Kakubin Sound Keychain A sound keychain that lets you hear Koyuki's voice singing "Whiskey ga Osuki desho~♪"! It's been opened and the battery is dead, so a battery replacement is needed. Since I haven't confirmed its operation, I'm selling it as a junk item to someone who understands this. It starts with the sound of ice hitting a glass, "Whiskey ga Osuki desho♪" Sound Keychain - Model Name: Suntory Sunlight - Type: Keychain - Design: Bottle-shaped - Color: Brown - Accessories: With chain Thank you for looking.
