KNITPRO Karbonz fixed circular needle is a ready-to-knit circular for working in the round or flat while keeping stitches supported on the cable. This variant is 7.0 mm (US 10.75) on a 100 cm (40 in) cable, making it a practical choice for hats, cowls, sleeves, and other projects where a circular needle helps manage stitch counts. Coil the cable loosely between uses, avoid sharp bends or heat, and keep the join free of lint to reduce snags and twisting.
