Hi there, I make fingerprint jewellery and have made a few pairs of cufflink without complaint. However one of the very first pairs I made came back to me as one of the backs had come off and the cufflink disappeared. So I made another one free of charge.

They've just come back again as the hinge on the back of one has broken... does anyone know if I can repair it? Is there a way of removing what's left of the back and the solder etc. and then I can put a new one on?

Am already running at a loss on this particular pair so don't want to have to start from scratch!

Any advice welcome....
