Knitter's Pride, 40" SmartStix Circular Needle: US 6 (4.0mm)
SmartStix are a knitting needle and ruler in one, as each one is laser marked at 1 inch intervals along both the needle and the cord. This makes measuring your gauge and project easier as you no longer have to search for your tape measure while knitting.
These lightweight aluminum needles are smooth to the touch and expertly tapered to the tip. They feature laser printed sizes, a smooth join and resilient cords that lay flat with no kink or twist.
This 40" length needle is popular for projects with a large circumference or length- baby blankets, shawls, scarves. Also used for the magic loop method.
