SINGER 21495 Class 15 Threaded Bobbins, Transparent, Assorted Colors, 12-Count

Perfect, I was going to do my own but this was so much easier to purchase and work very well!!

Excellent!!!

Great color variety for when you’re too lazy to wind your own bobbin. Durable and works great with my machine.

This item was purchased for sewing machine. I really like that it is pre- threaded with different colors haven't used but.. it should work very m well.

Neatly provided with a variety ofColors. Shipping was fast and these are a realTimesaver. Reasonably priced.

Very good, easy to use, and varied colors. Useful for adjusting costumes for a play.

I bought 2 Threaded Bobbin Packs, since the pencil case-sized emergency sewing repair kit at my children's house also needed a selection of colored threads.I couldn't find the dimensions of the bobbins case here or on the internet, but the received bobbins case measures 3-3/16" L x 2-1/8" W x 1" H.

Pros: Perfectly acceptable if your machine accepts Class 15J BobbinsCons: This package of 12 transparent plastic bobbins is manufactured under the Singer label as Class 15. It is unfortunately mislabeled. The bobbins in the package are class 15J, a slightly different size and shape. It may work if your machine says it accepts 15J, but it may not work if your machine says only Class 15.
