Isacord 1000公尺 聚酯纖維 1375 深炭灰色線

Finally, a thread that doesn't fray or break mid-project. The 1000m spool has been perfect for my commercial embroidery machine, handling intricate designs without any tension issues. The dark charcoal shade looks incredibly rich against lighter fabrics.

This 1375 dark charcoal color is perfect for blending into black denim projects—absolutely no bobbin issues. The polyester feels smooth and runs beautifully through my machine.

The tension stayed steady through a full 50k stitch run, and the color is a true dark charcoal that blends nicely with most black fabrics. The polyester strength is noticeable when doing dense satin stitches, no snapping or fraying at all.
