Knit RED's 30cm circular needles are made from surgical-grade stainless steel with a smooth, satin finish. Their red, shape-memory-free cable is composed of multiple nylon-coated steel strands, allowing the yarn to glide effortlessly. The precision-machined, slightly curved tips are designed to reduce hand fatigue. The size is permanently laser-etched onto each needle. And the joins? Remarkably smooth!
