Exquisite Thread Mandarin ES520

40 weight.  1000 meters. Poly-X40 comes on a convenient snap spool and offers all the great characteristics of a polyester thread. It’s durable, has a high sheen, and is perfect for embroidery. It’s almost twice as strong as rayon, which means it runs longer without thread breaks or unraveling, while providing just the right amount of elasticity to minimize looping and puckering.
