Didn’t suit my needs

I picked these bobbin clips up for next to nothing at my local thrift store. I figured that for all they cost it was worth checking them out as an organisational tool for my sewing threads. Well, they just didn’t work out for me so they can go back where they came from. I am not sure what sewing machine bobbins they would work for because although bobbins vary in shape, to my knowledge, they are all a similar size. These clips would not go through the hole in mine. It was worth a try and the dollar I spent on them went to charity. Maybe someone else will purchase them and the charity will double the profit. Either way I have regained a little space.
