KNITPRO Nova Cubics double pointed needles are made for knitters who want an ergonomic square profile for controlled, comfortable knitting in the round. This set includes five 20 cm (8 in) needles in 5.50 mm, designed to help keep stitches steady while you work small-circumference pieces. Use a standard needle sizer when switching sizes, and store the needles dry in a case to help protect the polished finish between projects.
