The Canela Cose, 15mm and transparent, is a clear plastic bobbin for sewing machines, used to wind and feed the bottom thread during sewing. The transparent material allows you to quickly check the amount of thread remaining without having to remove the part from the machine, avoiding interruptions in the middle of the work. The 15mm size is compatible with various models of domestic sewing machines, making it essential to always have spare bobbins available to quickly change thread colors. It is a basic and indispensable accessory in any sewing kit.
