KLASSE-5 German-engineered steel machine needles size 80/12. The large specially coated eye allows delicate metallic thread to feed freely at high speeds while the large groove prevents splitting burning shredding and thread breaks. Best for: machine embroidery with metallic thread on woven or knitted fabrics. Also suitable for general purpose sewing with the larger eye being easier to thread. Use with metallic monofilament/nylon and other decorative thread.
