Carbon fiber, also used in airplanes and automobiles, is characterized by its tensile strength and light weight. These Carbonz series knitting needles, with brass nickel-plated tips, offer not only lightness but also an unprecedented smooth needle movement. This series is very high-performance within Knit Pro, and comfortable to hold. Knit Pro products are made overseas, so quality standards may be less stringent. There may be variations in needle tips and lengths, scratches, burrs, rough sewing, and damage to the packaging. Please be aware of this before ordering. #yaoknitpro → You can see all of Yao Kobo's Knit Pro products. #yaosan → You can see all of Yao Kobo's 3.0-3.9mm (size 3-6) needles.
