HiyaHiya, 9" Bamboo Circular Needle: US 4 (3.5mm)
With flexible cables and smooth joins, these smooth and strong bamboo needles are warmer to the touch than steel and allow stitches to slide of a bit less easliy if you are concerned about dropping them. A great addition to any knitter's toolbox.
This 9" length is popular for knitting socks, cuffs of sleeves and other items with a small circumference.
