KLASSE microfiber machine needles feature a very sharp point intended for precise stitching on tightly woven and fine fabrics. This cassette includes needles in assorted sizes 60/8, 70/10, 80/12, letting you match needle size to delicate fabrics, sharp corners, and finely detailed seams. Use them for microfiber, silk-like synthetics, and fine quilting cottons when clean penetration and accurate stitch placement matter.
