Genuine Japanese product: TetherTools * TetherPro USB-C to USB-C (4.6m) Right Angle * TetherTools TetherBoost Pro USB-C Core Controller Extension Cable (5m) Set of two. The black extension cable was used regularly, but the orange cable was used as a spare, so it's almost unused. Both have been tested and confirmed to work with a Mac and Capture One. When using, connect the black extension cable to the PC side and the orange cable to the camera side. This will give you a total length of 9.6m. If you have any questions or requests, I will answer them as best I can. Thank you for your consideration.
