Using these KnitPro Mindful Fixed Circular Needles is easy. Just pick up the needle and start knitting your project, whether it's a delicate lace pattern or an everyday scarf. The marked cables can help you measure your work as you go. When you're done, gently clean the needles with a soft cloth. Avoid using harsh chemicals as they may damage the printed words. Store the needles in a dry place to prevent rusting. And don't worry about the package change; the quality of the needles is still top - notch.
