addi Rockets join the best of two worlds: the smooth, nickel-plated finish from addi Turbos, and the sharper tips from addi Lace. The result is a smooth-handling needle that is perfect for intricate stitch work. The size and length are printed on the flexible, blue cable. The longer, forty inch length is perfect for shawls, edgings, and other projects where a lot of stitches need to be on the needle at the same time.
