Knitter's Pride-Cubics Platina Interchangeable Needles. Engineered from hollow brass pipes and plated with chrome making the shiny smooth surface a delight. The cuboid shape in cross section eventually gives way to perfectly tapered brass tips. The unique ergonomic shape provides excellent grip & uniform stitch definition. Smooth joins allow for snag-free gliding of stitches. Cords are flexible and lay flat with no kinks or twists. The Special needles are 4 inches in length and are used with the 16 inch cord (sold separately). They are ideal for hat making and smaller diameter knitting projects. This package contains interchangeable needles in size 8/5mm. Imported.
