Review on Paxcoo 50 Pcs Bobbins and Sewing Thread Set with Case and 2 Pcs Soft Measuring Tapes - Assorted Colors (Compatible with Brother, Singer, Babylock, Janome) by Amanda Castillo

I have a Singer Stylist 7258 which uses a 15J bobbin (bought the machine from Revain and love it) and these bobbins fit and sew perfectly. I'm surprised because they are really different from the ones in the car. My photos have "Singer" written on the spool on the left and one was in my car when I bought it. The machine also came with three extra spools, the one in the middle of the picture is one that doesn't have the beveled sides like the Singer. The right one was in a Paxcoo case. Then Paxcoo is the same as 15J. I love these pre-threaded coils. I just wish there were more white, black, and navy blue to pin down instead of so many weirdly similar colors. But what a time saver!
