These KNITPRO Karbonz single point needles are designed for knitters who prefer traditional straight needles for steady, back-and-forth fabric building on detailed patterns. Each needle measures 35 cm (13.8 in) long with a 3.5 mm (US 4) size that suits fine to light-medium yarns, giving room to work long rows with consistent tension. Their balanced feel supports comfortable hands on longer sessions while helping you keep stitches uniform across repeats, shaping, and finishing work.
