SINGER Class 66 Metal Bobbins, 4 Count

I purchased 2 packages of 4 Singer bobbins each. I opened both packages and mixed them together, not realizing they were not the same size. 4 bobbins fit my Singer machine and 4 was just a little too large. I put one in my bobbin case and could hardly get it out. In the mean time, I had thrown away both empty packages and the receipt so could not return them. 4 of them worked great.

They do not fix my old Singer 500A..yes they were a size 60, but once I put it in the bobbin holder it would not spin or could I pull the thread. I have purchased several of these bobbins and yet none will work. I have to use the same 2 old bobbins over and over

I bought 2 packages of these to put into my grandmother's old Singer 403, It said that it took class 66 bobbins. Well each time I tried sewing, the bobbin would stop and cause my bobbin thread to snag. Then when I tried taking them out of the machine my husband had to use something to pry them out, they didn't slide easily in and out like all my other bobbins. Thank goodness I only spend 98 Cents per package because I threw them out, they were all bent up. Went to Joann's and bought the dritz brand, Class 66, they worked perfectly.

the metal bobbins are smaller than the plastic ones that cam with the machine - they don't match

These were too big for my Singer 99, even though the machine takes this type of bobbin. I'm sure Walmart will take them back though, so that's good.

I also purchased 3 packages but I was not so lucky. Mine were all slightly too large. I also turned each one on its side and they all wobble across the table. Not put together properly. Why do they cost 97 cents in the store and 52 cents on line?

I bought these for my vintage Singer 201-2, which is supposed to take class 66 bobbins. These are larger than the originals! It almost got stuck in my bobbin case. These are supposed to be your own brand. How do they not even fit your own machines?? Also, the window was open near where I had these and it rained overnight. One of these bobbins started to rust in the middle immediately.

I purchased these bobbins for my vintage singer sewing machine. I cant even wind the bobbin. the hole does dont fir on the winder. they are all different sizes. I did find one in the 4 packages i purchased that fit the post. but the little hole doesn't line up so it wont wind. Wish I would have read the reviews before I purchased. Funny I had an associate help with hte purchase. Very disappointed

This bobbin is not a type 66 bobbin. The hole for the winder pin is roughly 1mm farther from the center than it needs to be to fit the bobbin winder on antique machines. The only good point is that if you manage to get the bobbin wound, it will work for sewing. If I can't return the open package then I'll try drilling new holes on a drill press.
