Super Bobs MasterPiece コットン80ヤード プリワウンドボビン 12個入り クラス15 ビスク

I was pleasantly surprised by how smoothly these bobbins feed through my machine, and the 50 wt. Egyptian cotton thread feels incredibly strong with no lint buildup. They're a perfect fit for my Class 15 setup and save me tons of time.

The 80-yard length on these is a real time-saver, and the Egyptian cotton thread is noticeably smoother than the standard stuff I've used before. They load into my machine without any fuss, though I do wish the bisque color matched my fabric better.

For my vintage Singer, these bobbins fit perfectly and the cotton thread is much smoother than what I was using before. I've already gone through two of them on a single quilt project and the tension stayed consistent the whole time.
