Can I use these in a top-loading machine?

No. These cardboard-sided bobbins are for front/side loading with the bobbin upright. They are not for top-loading/drop-in machines with the bobbin lying flat.

Will Size L fit every machine from a listed brand?

No. Bobbin size can differ between models of the same brand. Check your exact model in the compatibility chart in the product photos, then confirm the loading design.

What comes in the box?

144 black prewound bobbins. Approx. 115 yd (105 m) per bobbin; 16,560 yd (15,142 m) per box. Thread lengths are approximate.

What do the thread labels mean?

75D/2 filament polyester is also labeled #120 / approx. 60WT; nominal Tex 17, Denier 150. These are approximate commercial labels. The material is polyester, not cotton.

Why choose filament bobbin thread?

It holds more thread per bobbin than our Size L Spun Polyester options. Its very smooth surface helps the embroidery top thread tighten evenly and lie flatter. Test tension on scrap fabric first.
