If you are struggling with DPNs or you are wanting to try a new way to knit socks or other small circumference items, the ChiaoGoo 9 inch circulars are awesome. We love that we don't have to wrestle with several needles to get knitting! Just cast on and away you go. We use ours for socks, sleeves, mittens, baby items...
Now, these needles are smaller than what we are used to but they are great once you get over how little they are. The needles are 2" long, attached to a 5" cord.
The ChiaoGoo 9" Circulars are made of Stainless Steel, have the same memory free cable that we all love & have the size laser engraved on the side of the needle.
