The needles feature a burr-free and stamped eye. Their finely tapered tip is slender, and together with the smooth surface, they glide through all fabrics. Additionally, the matched spring hardness allows for smooth operation without bending or breaking. Typically, the long needles are about 7 mm longer and are used more for common sewing tasks due to their better grip. The half-long needles, favored by experienced users, are often chosen for more demanding sewing projects; their quicker penetration makes them just right for the job. The shape of the needle head also allows for easy handling without a thimble.
