For the knitters who want it all and more... addi brings you individual pairs of Turbo interchangeable needle tips! Add to your existing Click set for more project potential, or take the plunge and begin building a set if you haven't already! Click Tips require no tools to change; simply insert the cord into the tip, twist and release. The tips will remain secure until you change them. Click Tips are nickel plated by way of an electro-static process, which produces a smooth, rounded edge, where the tip and the cord "click" together. Note: While the 24", 32", and 40" cords from the Click sets are fully compatible with any style of tip, the new 16" and 20" cords are not compatible with the Turbo® tips. The length of the Turbo® tips combined with these smaller cords, will not allow for proper circular knitting.
