Review on HimaPro 144 Prewound Bobbins for Embroidery Machines Size L: Compatible with Brother, Babylock, Janome, Bernina, Husqvarna, Pfaff, and More! Plastic Sided Black & White - 50 Weight by Carrie Spencer

If you only have these options they will fit. However, you have a consistency problem. Some rolls are wound too tightly, others too loosely. The biggest problem is that many of them are wound too tightly and don't fit properly in the bobbin case. You can solve this problem by expanding the flow part. Currently halfway through the purchase and will not be buying again. Edit: My opinion hasn't changed, but many of the 1-star reviewers don't seem to realize that they aren't for everyday sewing, but primarily for machine embroidery. . If you want to make clothes out of it, look elsewhere, it's not made for strong stitching. Both sides of paper are standard and in some cases you can get them without sides. Paper is not a problem when used correctly. However, I still only recommend them as a last resort.
