Brother SA159 PQ 系列金屬梭芯

The metallic weight of these bobbins keeps the tension steady through dense quilting layers, and they drop into my PQ series machine without any wobble. I've already wound a dozen for a marathon project and the machine hasn't skipped once.

They hold just enough thread for a long quilting session without needing a refill, and I’ve had zero snagging issues since switching to these. The metal construction feels sturdier than the plastic ones I used before, which makes a difference in consistent tension.

These metal bobbins fit my PQ series perfectly and spin without any wobble, even at higher speeds during quilting. I've wound several and they all feed the thread smoothly, so my stitches stay consistent. Exactly what my projects needed.
