Description Metal Bobbin Version 2, three bobbins in one pack. The Janome HD9 Black Edition and the HD9 Version 2 take a new version of the Large Jumbo Metal 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. Keep a few on hand so that you can wind a new bobbin using the independent bobbin winder on the machine so that you always have a full back up on hand for when you do finally run out. The current Version 1 Parts and the new Version 2 parts are not compatible If your bobbin case looks like an almost full circle, these are the correct bobbins. If your bobbin case looks like a semi-circle you will need a different bobbin. For Janome Sewing Machine Models: HD9 Professional, HD9BE
