SuperBobs 聚酯纖維梭芯 12入 M型 深灰色

Finally found 60wt bobbins that fit my machine perfectly without wobbling, and the dark gray hides thread lint surprisingly well. Used them for a detailed embroidery project and didn't have a single tension issue.

The cardboard sides are sturdy enough that they don’t warp when I load them into the machine, which is a big plus for my embroidery hoop work. The dark gray shade blends nicely with most of my quilt backing fabrics, so I don’t have to swap threads as often.

I was worried about 60wt thread breaking, but these bobbins run smoothly through my machine without any shredding. The cardboard sides feel sturdy enough for multiple uses.
