GUNOLD - MAGNETIC BOBBINS [876L0100, ]
Part # 876L0100
Discovered this brand while surfing youtube on embroidery techniques and then looked for reviews on the bobbins. As reviews stated, more thread per spool than other brands and the fact that they are neatly stacked and arranged than loose in the box. My go-to brand now.
These bobbins are the worst I've ever used, after 31 years of embroidery, I've never used bobbins that don't stay within the tension adjuster, constantly pull out of the bobbin casing and will sew through an entire design without bobbin catching underneath! The second I switched back to a different brand all the problems stopped. I even threw away almost two full boxes of these they sewed so bad.
Great value compared to Filtec. 13 more yards, 44 more bobbins in box, and $7 cheaper
