Prym Bobbin ring - 5pcs

The Prym bobbin ring can hold up to 20 sewing machine bobbins to keep them safely stored. The bobbin ring prevents thread from unwinding and allows the threads to be found quickly and easily. The bobbin ring size can be adjusted by using boiling water to fit the size. If you put it in cold water after heating it will regain its original hardness so that it fits the bobbins that you want to store.
