We stock only the Special 16" Set in the Knitter's Pride line of interchangeable needle sets. Why? The Special 16" Set is the only set that has the 3.5" length tips that allow you to knit hats, neckbands, and most of the sleeve of an adult sweater. This set come with 2 cords to make a 16" (tip to tip) length. You can just add more cords to your set if you need longer lengths!
The Dreamz Special 16" Set has needle tip sizes from US 4 (3.5mm) to and including US 10 (6mm). They are made of polished wood that makes for a smooth surface and come in a range of colors for easy size identification.
The Platina Special 16" Set has needle tip sizes from US 4 (3.5mm) to and including US 10 (6mm). They are engineered from hollow brass pipes and chrome-plated, creating a shiny, smooth surface.
Knitter's Pride Swivel Tips may be the answer if your knitting technique tends to loosen the needle tips and cord.
