looking for magnetic backs for pins

[KansasCity]

Several years ago I bought Magnetic Disney Pin backs at Disneyworld. You just take off the black rubber backs and put these on. THe problem is that when i was at Disney last month, they do not sell them anymore. Does anyone have any idea where you can buy these or something that would work to make pins magnetic?

thanks

I have never seen these but they sound like a good way to secure the pins...

I have never seen these, only the locking backs. I'd worry about them coming off the lanyard, I'd imagine that you could pull the magnets apart pretty easily.
