Magnets for cases?

[bkb1777]

Hello everyone, long time follower not a huge poster. I have a question for everyone. Does anyone have a brand they recommend or know of any thing I could order essentially that would be a pack of magnets that I could use on multiple cases. Like say for example put on my Apple case on the inside, so something thin, but also safe for my iPhone. I have a mount and a case that came with it but I have a tendency to swap out multiple cases. Any help is appreciate.

Thanks!!

I bought a set of these from Amazon in the UK and I’m very happy with them. They’re very thin and the adhesive works well.

Incidentally, it’s only the mount that’s magnetic - the plates aren’t.
