Knitter's Pride, 40" Karbonz Circular Needle: US 4 (3.5mm)
A revolutionary development in knitting needles! This 40" circular needle is made from carbon fiber, which has high tensile strength and flexibility while being very lightweight and warm to the touch. This is the same material found in Boeing 787s, stealth fighters, and race cars.
The tips of the needles are made of nickel-plated brass to provide a smooth knitting experience.
