This is a set of four karaoke cartridges released by TAKARA. These cartridges are inserted into a dedicated machine to enjoy karaoke. Please refer to the photos above for the song list. * The photos don't show up well due to the lighting, so please search for "globe" to see the list. It also has a scoring function. Have fun with family and friends during the New Year's holiday! I apologize, but I cannot confirm the operation as I do not have the main unit. Thank you for looking.
