Bobbin Boat™ Trio by Dritz^® is a three-pack of bobbin holders that keep your bobbins securely in place. The curved interior of the boat "hugs" the bobbins for a snug fit. Bobbin Boat holds 10 Class 15 (Style A) bobbins, which is the bobbin size compatible with Ultrafeed^®, Leatherwork^® and many home sewing machines. With its curved design, you can toss it in your sewing toolbox and the bobbins will stay in place.

Note: This will not fit bobbins for the Big-N-Tall or Style M bobbin machines like the Sailrite® 111, Fabricator® or Professional.
