This is a one-seg receiver adapter for the Nintendo DS that allows you to watch TV. It can also be used with the 3DS. I received this as a shareholder benefit some time ago and used it once or twice before storing it away. After that, my DS broke, so I haven't been able to confirm its operation. (It worked without any problems the last time I used it) I will sell it since I no longer use it. The contents are all shown in the images. The contents are in good condition. The box has some stains due to aging. Please check the images. The box will be folded and shipped via anonymous delivery.
