Size 12/80. 5 needles per pack. Carded. - 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 coverlock stitches. *They have increased strength due to a reinforced blade leading to less breakage and straighter stiches. - Bernina L850, L890, Most Elna Sergers, Pfaff Coverlock 3.0, same as Singer style 2022
