Schmetz ELX Chrome Finish Ball Point 80/12 5-pack

Designed for use in electronic multi-purpose Sergers that do the overlock, cover, safety, and mock safety stitches. Machines should specify the ELX705 system - not suitable for use in normal home sewing & embroidery machines. Chrome Finish, Ball Point (SUK) Size 80/12 and 5 needles per pack. - Here's how ELX705 needles vary from home sewing needles. *Needles have a groove on the front side and back side of the blades to reduce skipped stitches. *The second long groove is necessary to create chain stitches like overlock and cover lock stitches. *They have increased strength due to a reinforced blade leading to less breakage and straighter stiches. - Bernina L850, L890
