This is a Suntory Old Sound Keychain from the 1950s (not for sale). When you turn the switch on and press the lid, the Old CM song "Yoru ga Kuru" (Night is Coming) used to play. It didn't play because the battery is dead. It used to play music before. I don't know the condition as it belonged to a family member, but please consider purchasing if you understand the current condition. It has been stored at home, so please purchase only if you understand this.
