Cose Sewing Machine Oil is a specific lubricant for the internal mechanisms of sewing machines, used to maintain the proper functioning of moving parts, reduce noise, and prevent premature wear due to friction. Regular application of a few drops to the points indicated in the machine's manual helps prevent jamming and prolongs the equipment's lifespan. It is specifically formulated not to stain fabrics, unlike generic lubricating oils. It is an essential maintenance product for anyone who uses a sewing machine regularly.
