The Gütermann Cosetudo 250m white 800 717878 sewing thread ensures invisible seams and perfect fluidity on high-speed sewing machines. The 250-meter bobbin in dense polyester is soft to the touch and extremely durable. The soft white/off-white 800 shade adapts beautifully to fabrics that are not pure white, such as raw silk, linen, and lace, offering a natural and elegant color blend.
