Hi all,

I made a pair of PMC fingerprint cufflinks a few weeks ago for a customer and she has emailed me the following:

"These cufflinks have started to really discolour. One of them has almost turned black. I dropped one out of the box the corner has turned black where it fell? Is this normal? "

I'm not sure why this is, and none of the cufflinks I've made for other people have done this. I don't know what to say to her or what advice to give. They have been made and packaged the same way as all my other cufflinks. Could it be due to handling? Does she just need to polish them? If so what should she use?
