Kollage Square Circular Needles are designed to be ergonomically suited to your hands to decrease stress and strain. They are perfect for slippery yarns, or if you knit tightly. If the super flexible original K-Kable didn't work for your knitting style, you'll love the new firm cable which is similar to most other circular cables out in the market, except a little softer so it’s ready to knit with right out of the package.
