Schmetz Overlock/Serger Needle ELX705 Size 14/90

Designed for use in electronic multi-purpose sergers that do the overlock, cover, safety, and mock safety stitches.
**Not suitable for use in normal home sewing machines or embroidery machines**
Machines must specify ELX705 system. Size 14/90. 5 needles per pack.
Here's how ELX705 needles vary from home sewing needles.
*Needles have a groove on the front side and backside 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 stitches.
