Spiral tube (white), manufacturer unknown. I bought it when I moved, but I didn't use it much and stored it. I think there's about 20m left, as I hardly used it. I'm not an expert, so I don't know the details, but the tube is about 10mm in diameter. The size of the box it's in is 300mm (length) x 300mm (width) x 170mm (height). *There are marks written on the box with a marker. The contents of the box are unused, but dust may have entered from the opening of the box, so please refrain from purchasing if you are concerned. When shipping, I will seal the holes and attach the shipping label directly to the box! #Wiring #Cable #ElectricalWork
