Invisible magnets - Avoided by high end luxury ?

Hello everyone,

Have you ever dealt with hidden neodymium magnets that:

1 - Broke inside a purse?

2 - Lost their strength over time?

3 - Damaged electronics, smartphones, or credit cards?

High-end luxury brands like « H » seem to avoid using them, and Peter only used them once in a Metro pochette. Is there a reason for that?

I'm considering using them in my upcoming design, but their brittleness is a concern. I've come across magnets coated in rubber or epoxy, and some encased in steel, but these options add unwanted bulk.

If your were aiming at lifetime longevity for a high-end item, what solution would you go with?

Thank you in advance !
