5, 20 or 50 Silver Tone Brooch Backs 25mm 30mm safety bar pin badge broach
£7.49
If you are buying to put on the back of a brooch you'd normally go down in size a little ( ie : if the brooch you have is 30mm then you'd use a 25mm/27mm back on it so that the clasp or hinge on the brooch back isn't visible).
