Thank you for viewing. This is a KOWI URK-232 release for Sony cameras. I bought it as a spare, but the camera's connector was faulty, so I switched to a wireless one and no longer need this. I have never used it, but I threw away the box, so I'm selling it at a low price. - Brand: KOWI - Model: URK-23 Although it is new, it has been stored at home, so I hope those who understand that it is a used item will consider purchasing it. Thank you.
