Designed and developed in Germany, Klasse needles are engineered to meet the most exacting industrial performance standards.  Klasse needles go through 155 quality checks, earning high industrial quality rating for: stability at high speeds, seam appearance, clean stitch holes, and precise and uniform stitchability.  A unique curved design at the critical clearance-above-the-eye stress point distributes pressure equally and makes Klasse needles much stronger than conventional flat needles.
