Description Metal Bobbin Case Version 2 The Janome HD9 Black Edition and the HD9 Version 2 take a new version of the Large Jumbo Metal Bobbin and an appropriate bobbin case to fit the bobbin. This Jumbo Metal Bobbin holds 40% more thread than traditional L sized bobbins. More thread on the bobbin allows you to keep sewing longer without interruption. This is extremely useful while performing high speed stitching. Having the appropriate sized bobbin case for your bobbin ensures smooth stitches and prevents thread breakage and interruptions. The current Version 1 Parts and the new Version 2 parts are not compatible
