There's a reason Purl Soho only sells Skacel circular needles: They're simply the best! Addi Turbos are their classic collection of nickel-plated, brass-tipped needles. They have soft, pliable cords and exceptionally smooth connections. From size US 000 to US 19, and from 8 inches to 60 inches in length (from tip to tip), build an Addi Turbo collection and put your knitting into "Turbo" speed!
