Each of these needles is made from rust-protected, hardened steel. The combination of a finger-friendly head, a burr-free eye, and a uniformly polished surface, along with the slender, tapering point, allows for effortless penetration through all fabrics. The spring hardness prevents bending or breaking of the thinnest needles, ensuring a comfortable working experience. This needle set meets all requirements for everyday sewing and mending tasks at home.
