The Canela Cose, 20mm and transparent, sold in packs of 4, is a transparent 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 20mm size, slightly larger than the 15mm reference, is compatible with a range of domestic sewing machine models. Sold in packs of 4, it is an economical way to always have spare bobbins available.
