These clear, twistable cordes are suitable for all LYKKE interchangeable needles. They are memory-free and do not buckle when you turn your needles! The measurements refer to the length including the needle tips. For example, a 32" cord is the size you would need for a 32" needle with 5" tips. So while they will fit 3.5" points, you would get a different needle length if you used them with 3.5" points. Each cord comes with a pair of stoppers and a tightening key. Set with one cord, 2 stoppers and a tightening key Made in Nepal
