Upgrade your needle gauge with this compact and modern new design from Cocoknits. It measures sizes US 0 (2.00mm) to US 15 (10.00mm). Needle gauge is created from 100% biodegradable PLA (polylactic acid) that is a plant-based plastic substitute. The rainbow-ordered discs click together with tiny magnets and the gauge measures approximately 1" by 1½" when closed. Please Note: While the color order is fixed, each needle gauge has a random starting color and may vary from those shown.
