This is an Otodel junction box. I'm selling it because I'm replacing my equipment. It's a passive type. There are some paint chips on the exterior, but there are no problems with its operation. In addition, there may be signs of use and small scratches that are not visible in the photos. Please refrain from purchasing if you are sensitive to these details. Velcro is attached to the back. There are no accessories other than the main unit. It will be shipped via Takkyubin Compact. If you have any questions, please feel free to comment.
