Bobbin case with 12 CB plastic bobbins

The heart of each sewing machine is the bobbin hook, with which the threads are knotted and are thus responsible for the quality of the seam. The system proven over decades with a CB hook for the central bobbin is ideal for home use and has been proven worldwide for decades. Prym offers the CB metal or plastic bobbins in a practical bobbin box with 12 units in each. In that way they can be kept always ready and well organised beside the sewing machine. The cover made of transparent plastic always allows a good overview of the colours of the threads and the quantity remaining.
