Baby Lock Mクラス ボビン ジュエルカネット: BLJ-BOB

I was worried about bobbin compatibility, but these lock in perfectly with no wobble in my BLCT16. The three-pack is a solid value for genuine parts that don't skip a stitch.

These fit perfectly in my M Class machine and spin smoothly without any wobble. The three-pack is a good value, and I’ve already noticed less thread jamming than with the generic ones I tried before.

Finally snapped up the genuine bobbins for my M Class after using cheap knockoffs—the precise fit makes a real difference in tension consistency. No wobble or skipped stitches so far, and three is the perfect starter pack.
