Operation has been confirmed. I'm selling it because I've only used it a couple of times and no longer need it. There are some marks, such as stains and pen marks, that occurred during storage at home. Please check the photos and if you understand, please purchase. Please charge it with your own battery. I can include the USB cable, but it has deteriorated over time and isn't very clean, so I will only include it if you request it. Thank you.
