Using these addi Turbo circular needles is a breeze. Simply thread your yarn through the needle tip and start knitting as you normally would. The smooth nickel coating will help the yarn glide easily, so you can work on your projects faster. When using the smaller needle sizes, keep in mind the non - standard sizing we mentioned. For maintenance, wipe the needles gently with a dry cloth after each use to keep them clean. Avoid using harsh chemicals or abrasive materials as they may damage the nickel coating. Store the needles in a dry place to prevent rusting. And be careful with the plastic needle tips of US 36 and US 50, as they can be more fragile compared to metal ones.
