Although this item is unused, the details are unknown because it doesn't have its packaging. I haven't been able to confirm its operation because I don't have an environment to use it. The length is approximately 150cm. I plan to wrap it in cushioning material and ship it via Yu-Packet Post. Although it's unused, it has been stored at home, so please refrain from purchasing if you are concerned about minor details. Cable length...Less than 1m to 1.5m #9683l #0nes_tar
