Prym Sewing machine bobbins

For machines with this type of spool, you will receive four identical sewing machine spools made of transparent plastic. The advantage of the plastic spools is the good visibility they provide. You can always keep an eye on the color of the thread and the thread supply on the spool, which helps prevent sudden shortages of the bobbin thread. These sewing machine spools are offered in the appropriate versions for the brands Janome, Brother, Singer, Bernina, Husqvarna, and Pfaff.
