Hembob Tex 90 Style M Bobbin Polyester UV Black is a prewound polyester thread bobbin. Hembobs eliminate the need to wind bobbins. Just drop them in the bobbin case and sew!

Note: Some hembobs are overfilled by the manufacturer. This might cause issues with your sewing machine. We recommend pulling off the first foot of thread before installing the hembob in your bobbin case. This will prevent any potential thread jams and will ensure that any excess glue from the manufacturer has been removed.
