Aluminum bobbins manufactured with the exacting specifications of Innova. You will find that each bobbin will give you the same tension as the other because they are EXACTLY the same size. This is more important than some people realize. If there is slight variations between bobbins the tension settings will need to be changed. You can avoid that with reliable bobbins.
