Madeira sideless pre-wound machine embroidery bobbins have no sides allowing for more yardage on each bobbin.
These L style bobbins have the same high quality polyester filament thread as other Madeira 308 bobbins. At 150 yards per bobbin, you'll find that you do not have to change your bobbins as frequently. With no sides, it is easy to see at a glance how much bobbin thread is left. You'll find less build up in your bobbin cases when compared to other side-less bobbins. Each bobbin has 150 yards of continuous polyester filament thread. Contains 144 per box.
