Teijin Mighty Tetoron Thread Thread Thickness: 50s (for medium to heavy fabrics) Earth Colors: 30 spools total *Some colors have 1 spool, others have multiple. This sewing thread is easy to use with home sewing machines and sergers. These were acquired from someone who enjoyed handmade crafts, and I've gathered natural colors, mainly brown and green, from the same manufacturer and with the same thickness. This is a thick thread with a strong luster unique to Tetoron. It can be used for various purposes, such as emphasizing stitches, machine embroidery on denim fabric, or for crafts and doll hair. Although the damaged parts of the outer circumference have been removed, there may be fine dust accumulation and aging on the thread core due to long-term storage, so the condition is listed as "slightly damaged or dirty." Also, dirt is visible on lighter colors. It won't be noticeable during sewing, but if you are concerned, please refrain from purchasing and consider buying new thread. Will be shipped in a water-resistant package and cardboard box. I primarily use the post office during weekdays, so it may take a few days depending on the timing. Please refrain from individual sales or price reductions. *Regarding the used sewing thread currently for sale, please see the end of my profile.
