Everything in the image is included, and there are no other accessories. (Batteries are not included either.) This voice changer was released by TOMY in 1988. You can speak into the microphone and change your voice to sound high-pitched or low-pitched, like a processed voice! I received it from a relative, but I don't have a chance to use it. If you like Showa-era retro items, or if you're a collector, how about it? ^ ^ It's an old item and a used item from a private seller, so please consider it only if you understand. ^ ^
