The chic design, which combines the beautiful dark brown wood grain with the color of the cord, exudes a sense of luxury. ROWAN's birchwood needles are incredibly smooth to use and durable, and are made from wood that is certified as sustainable by the Forest Stewardship Council (FSC). The high-density birchwood is laminated to prevent deterioration over time, allowing you to enjoy the smooth knitting feel for a long time. Make these special circular needles with the ROWAN logo your best friend. In Japanese size measurements, they are close to the thickness of a size 15 needle.
