KNITPRO Ginger fixed circular needles are designed for knitting in the round or flat on hats, sleeves, socks, and smaller-width pieces. This item includes one 40 cm (15.7 in) fixed circular needle in 3.5 mm (0.14 in), made with warm laminated birchwood tips connected to a flexible cable. Wipe clean and store flat; the compact length helps manage stitches on shorter circumferences without extra cable slack.
