Well sorry for the long delay, things got a little crazy and didn't get shipped. But I finally got the magnetic back in. I ordered the 3 magnet set into plastic that was suggested earlier. Very strong magnets, so I think these will work nicely for a kilt pin. I ended up having to get 30 as they ding you extra $$ if the order is not over so much. I want to keep 5, so the rest are up for grabs to the people that wanted them. $0.75 / each plus shipping (I gotta figure out if I can send these through USPS easy or if I have to do something special since the magnets are pretty strong).
