These cool tools allow you to knit in the round without having to muss around with double-pointed needles. Instead of using four or five DPNs to knit a small circumference, you can use just three of the FlexiFlips.
Check out tutorials and videos on the website if you don't believe me. It's a lot like knitting on DPNs but with only two needle changes. And you don't have all the extra needle cable hanging out like you do with two circulars or magic loop.
It's a great way to try socks if you've been resisting because of the DPNs. We have them in metal and bamboo, so you can choose your favorite and get knitting!
