The Japanese company, Nagai Yoriito, have spent over 100 years developing their sewing machine threads to be used for applications in leather goods, sporting goods, industrial equipment and apparel. Their threads feature long lasting colors, composition and strength. They can be used in products as delicate as garments or as rugged enough for a Mars explorer probe.
