Please use a color search color chart to verify the exact color yourself. The image appears yellowish due to overcast conditions and lack of direct light, but the actual color is a more typical orange, a bit softer. Images often have discrepancies compared to the actual product due to the amount of light and the time of the photo. There are no noticeable stains, but I may have overlooked some light soiling from storage. Please forgive me. Shipping costs are usually higher than the product price, so purchasing multiple items together is more cost-effective. Discounts for two items will be minimal as shipping costs will increase. Spun Industrial Sewing Thread 100 size, for 3-thread overlock machines T O Y O B O (A-164) Orange Approximately 600 grams total for 3 spools Each of the 3 spools has over 200 grams remaining, so I believe they are about 90% full. If you use a 4-thread overlock machine, I can include empty bobbins (used, from other manufacturers) if needed. Please let me know via message. Otherwise, I will ship the 3 spools as is. Please be sure to verify the exact color yourself. The images are for reference only. These are 10,000-meter spools, so there is plenty of thread remaining. The above color description is based on the seller's subjective opinion.
