ve all the colors on prewind. makes changing bobbins easier when working on a project

The colors are good a d there ate a lit of white bobbins. Work excellent on my Brother’s machine.

Works great in my machine

I have trouble winding bobbins tight enough on my sewing machine and end up with bird’s nest underneath the fabric which is SO frustrating!! I’ve discovered prewound bobbins don’t do that in my sewing machine. Love the convenience and range of colors included in this selection. Will definitely use again.

Good price when I bought these

I could not get them to work on my Viking Topaz 30 nor my Singer model #4275, they do however work wonderfully on the Brother machines at my daughter's house.

My wife still hasn’t used all of it!

They work great in all my machines
