American & Efird Maxi-Lock Cone Thread Spool, White, 4.5 x 2.75 x 2.75;

American & Efird Maxi-Lock 100% polyester quality thread for the serger. Maxi-Lock is used by major serger manufacturers to test their machines and to demonstrate them in retail settings before each sale. Its soft finish disguises a strength that holds up under the most vigorous seam work. Its consistency, beginning to end, makes it easy to set and maintain tensions. Maxi-Lock meets the demands of serger sewing like no other thread, withstanding the high speeds and tensions that are unique to serging. This product is available in white color and 6000 yards cone.
