A pack of 25 special edition blue coloured 'J' plastic bobbins with decorative motif case. The Janome 'J' bobbin are made of a special rubber and plastic combination which allows them to better hold threads, absorb machine vibration and reduce noise. They fit most standard Janome sewing machines, except the MB4 and 1600 series machines.
Replace any bobbin that is worn or nicked: a damaged bobbin can cause sewing problems. Only use a plastic bobbin if your machine originally came with plastic bobbins.
