I watched this after purchasing it and then stored it. I have confirmed that it works and produces sound. It's relatively good. There are four cartridges, some with the plastic case and some without. The cartridges themselves are not particularly affected. The remote control is usable. I will include new batteries used for testing. Please purchase only if you understand that this is a used, aged item. #BANDAI #LittleJammerPro #Orchestra #LittleJammer #Cartridge #Toy
