Bests & Worsts Reviews from Amazon

I have a Brother SE400 and the inner diameter of these bobbins is too small to fit on the bobbin winder. I ordered two packs and tried several from each bag just to be sure. Although they look exactly like the bobbins that came with my machine, they are too small. They are packaged in a cheap, zip lock bag with a bar code and style number printed on a label and crookedly slapped on the bag. The style number, SA156, matches that recommended in my machine's instruction booklet, but these do not work. Normally, I wouldn't ask for a refund for something less than $10, but it's the only way the manufacturing or packaging defect can be rectified. I've posted two photos above.
