UNIQUE | 4 Hole Metal Bobbins

Finally, bobbins that don't warp or catch on the machine—these slide in perfectly every time. The 4-hole design actually helps keep the thread tension steady during longer sewing sessions.

Switching to these metal bobbins from the plastic ones made a huge difference in how smoothly my Singer runs. The 4-hole design keeps the tension consistent even at higher speeds.

These metal bobbins fit my Singer perfectly and the four holes make winding much easier. The build quality feels solid, no rough edges like some plastic ones I’ve used before.
