KNITPRO Nova Platina fixed circular needles are ready-to-knit circulars for projects worked in the round or across long rows, from hats to shawls and blankets. This option is 100 cm (40 in) end-to-end with a 3.00 mm (US 2.5) needle size to support the gauge specified in your pattern. Store the cord loosely coiled to help prevent kinks, and knit a small swatch first so your finished measurements stay on track with your chosen yarn.
