It's a risk, but:

It's on your body.

It blocks a view to the phrase unless it's taken off and seen with magnification.

You should know your seed phrase anyway, and I view any of these things as a backup in case you die or are incapacitated, therefore, it's a secondary mechanism, not a primary mechanism.

So, yeah, it's not perfect, but, I think I prefer that idea to many of these kinds of cards, though, the cards are certainly much more convenient to stamp or engrave.

There are lots of ways to do this, and it's kind of exciting! 😁
