Using these ChiaoGoo double pointed needles is a breeze. Just thread your yarn through the tapered tip and start knitting your desired pattern. When working with them, be gentle to avoid bending the needles. To clean, simply wipe them with a soft, dry cloth. Store them in a safe place like a knitting case to prevent any damage. And remember, since they're recyclable, when it's time to replace them, you can do so in an eco - friendly way.
