Please read the product description to the end as this item has been stored for a long time. Please consider that there may be faint stains and scratches that do not show up in the pictures. Therefore, I have marked it as having scratches and stains, but I believe they do not affect the seams. Industrial sewing thread #50 Milene 100% polyester Light gray (812) Approximately 45 grams The individual threads do not stand out much, so I think it is a relatively easy-to-use color with a wide range of applications. The above color is the seller's subjective opinion. Please check the color number in parentheses for the exact color using a color search or color chart. Please refrain from complaints about the color, such as the color being different from what you saw. This item was purchased in bulk and had been covered in dust. I have cleaned it. The plastic core also shows discoloration due to aging. Can be used with a home sewing machine. It is easiest to wind the thread onto a bobbin as needed and use it for the upper and lower threads. Or, please refer to the images. I cannot offer a discount. Please refrain from asking for a price reduction.
