KNITPRO Jumbo fixed circular needles are intended for super bulky knitting where oversized needles help form large stitches quickly and consistently. This fixed circular needle is 120 cm long with a 30 mm needle size, suited to thick yarns and statement textures in blankets, rugs, and oversized accessories. Choose a circular length that supports your stitch count comfortably, and keep the cord loosely stored to reduce stress during storage.
