"JUMBO BobbinSaver® is a larger version of the well known BobbinSaver® which stores sewing machine bobbins together for easy retrieval. Made of the same flexible plastic, this big brother JUMBO BobbinSaver expands to fit snugly around metal or plastic bobbin measuring at least 1-1/16 in. in diameter (bobbins not included). This Jumbo size accommodates the Series 7 and 8 BERNINA bobbins, as well as some other industrial machine bobbins. (Not compatible with Class M bobbins.) Bobbins are held securely and threads will not tangle or unwind."
