Love my cubics both the sock & interchangeable's butttttttttt they have a flaw, after knitting for a few hours the size notation on each needle was worn off; this didn't please me as having to chase down a needle sizer to check your needle size gets old very soon I knew something was needed to more or less keep the printed size intack , but what? In looking through a drawer one day there was my answer a common everyday item most women have "clear nail polish" I tried it on one needle it worked with no harm to the needle and the printed size was very readable and not worn off. My recommendation is cover your needle size on your needles when you first take them out of the package and their will be no more hunting down a needle sizer.
Knitters Pride Cubic needles are so much easier to use with considerable less pain when you have arthritis. I am now using both the interchangeable and the sock needles getting a lot more knitting without the intense pain I was having.
