Carbon Fiber Tube is used of high-tech carbon fiber composite material. Carbon Fiber is perfect for construction that requires great strength without excess weight. 100% Carbon Fiber Bar, high strength, corrosion resistance, surface smoothness, straightness good, stable performance. Its specific strength and elastic modulus are actually higher than carbon steel, yet it is lighter than aluminum. It has good electrical conductivity and very good tensile strength. Decorative carbon fiber tube at the same time has the appearance of 3D effects. Material: Carbon Fiber Length: 400mm / 15.7 inch Diameter: 2.5mm Package Content： 10pcs x Carbon Fiber Bar
