Description
The bobbin is the heart of every sewing machine, as it is responsible for knotting the threads, and thus for the seam.
The proven CB-bobbin for the central spool has been the most widely used system for decades and is well suited for home use.
Prym offers these CB spools made of metal or transparent plastic.
Both variants have a diameter of 20.5 mm, a height of 11.7 mm, and can be supplied as plastic spools in sets of 4 and as metal spools in sets of 5.
