MAGNETIC SIDED BOBBINS
All-rounder bobbin thread with improved performance for all MADEIRA upper threads. With a plastic core and side windows, one of which is magnetized. Insert the magnetized side back into the bobbin case. You can take full advantage of the even process by removing the brake spring * from the bobbin case. This results in an even more even withdrawal of the bobbin thread from the bobbins.
