This was not the item I ordered; I needed bobbin washers for a drop in bobbin case NOT a snap In case. At first thought they could be used ,upon further research realized they can not! In communication with Tim; he said I would need to return product at my expense and then I would get a credit. Baffled why I should pay for return shipping when the error was not on my end. I am disappointed and discouraged that a company would not honor shipping on this incorrect order. Regards, Dianne Chauvin
