Crystal Ice 10" Jumbo Knitting Needle Pack features beautiful crystal clear knitting needles. We have tested these needles and they are like knitting with crystal clear ice cubes, yet warm in your hands. Slick , easy to work with. The clear color makes it so much easier to knit on darker colors of yarn, and easier on more detailed and intricate work. What a wonderful concept! We absolutely love the ease in working with these, as well as the lighter weight , so as not to make it too heavy on your hands. Set includes 1 pair of each size: Size 11, 13, 15. (8.0, 9.0, 10.0 mm).
