The KnitPro Nova Metal Interchangeable Needle Deluxe Set includes four cables (60, 80, 100 & 120cm), giving 32 circular needle size/length combinations - the majority of your needle requirements covered in one set! Nova metal tips are made from nickel plated brass - with a smooth needle surface and cable join, the gradually tapered needle tip is great for fast knitting. Nova tips are perfect for complicated stitch patterns. Cables have very little "memory" making them fantastically flexible. Interchangeable knitting needles give you the combination of needle size & length you need, when you need it. Using the tips & cables in this KnitPro set you can have circular needles up to up to 120cm or very long straight needles. If you"re using a pair of tips for one project but simply have to cast on another using the same size, just unscrew the tips and replace with cable caps. Cable lengths refer to the overall needle length with tips attached to the cable. There are also eight end caps and four cable keys. The clear vinyl pouch has seven needle pockets on each side, giving plenty of space for extra pairs of tips & other accessories.
