Braided Waxed Thread

Braided waxed nylon and polyester thread (cord) improves water and mildew resistance, adds lubrication for easier sewing, increases stitch strength, limits stretching, and gives a slightly glossy look. These qualities make waxed thread a great choice for projects that require strong, long-lasting, water-tight seams. Because of waxing nylon and polyester work equally well for most applications.
It's an industrial thread for shoes and leather products, mainly used in leisure shoes,girl shoes,sofas and all hands sewings.
