Prym Metal Bobbin, in a pack of 5 units, reference 611350 I, is a metal bobbin for the bobbin case of a sewing machine, where the bottom thread of the stitch is wound. Prym is a German brand founded in 1530 in Aachen, the oldest family-owned industrial company in Germany, now headquartered in Stolberg and recognized worldwide for needles, pins, buttons and sewing accessories. Metal is more resistant to wear than plastic, maintaining its shape even after many cycles of winding and unwinding thread. It is a preferred option for those who have a sewing machine compatible with metal bobbins and need to replace this consumable.
