Description
The rotary hook and the double rotary hook are the most robust and easy-care systems, which are mainly used in high-end sewing machines and industrial sewing machines. Prym offers the matching bobbins for the small rotary hook and the double rotary hook in metal (five pieces each) or transparent plastic (four pieces each). The transparent plastic bobbins help you keep an eye on the color and supply of thread, while the metal bobbins have a significantly longer service life due to their material robustness. Sewing machine manufacturers that use this system include SINGER, DÜRRKOPP, PFAFF, and MEISTER. Diameter 21.9 mm, height 9.0 mm
