The interchangeable Seeknit CURVE needle tips are designed with a sleek, flowing form that embodies ultimate knitting comfort. The smooth polished surface ensures seamless yarn movement, allowing you to experience the joy of knitting exactly as you envision. Needle sizes are laser printed into the needle tip, so they won't rub off. The seamless connection between the bamboo needles and the stainless steel fitting is achieved through precision screws. The cords connect seamlessly to the fitting and include a swivel function.

Two different screw sizes, M1.8 and M2, are used for the full size range of Seeknit Curve Interchangeable needles. Compared with conventional products, the selection of cords, joints, and stoppers has been made easier. M1.8 screws fit together with needle sizes 2 mm / US 0 to 3.25 mm / US 3 while the M2 screws are used for needle tips ranging in sizes 3.5 mm / US 4 - 10 mm / US 15. 

The use of durable and flexible nylon cord enhances your knitting experience. The swivel feature helps to keep the needle firmly in place and prevents knitting from twisting.
