Crossing borders with seed phrase stamped on metal

Howdy doo

I am packing up my life and going to be travelling around for a while.

I've stamped my seed phrase onto a small piece of aluminium, probably about 6"x2", as this seems better than a flimsy little bit of card.

I don't want to leave it with the rest of my stuff as I don't have a high security lock up (it's at a friend's farm in a mobile container) however, my question is, when I'm travelling , assumedly this will show up thru my bag on metal detectors and is likely to draw unwanted attention from airport security...

Oh what's this?

Uhh my seed phrase for my bitcoin

Seems to defeat the purpose by drawing attention, and I wonder if some uneducated cross border security might even think you're doing something illegal.

I'm going to Asia and Europe most likely.

Or am I overthinking it. Less concerning but still a worry is travelling with such a thing. I'd have to keep it in my bag with me at all times I guess, it just scares me to think I'm essentially carrying around most of my BTC everywhere I go.

Any thoughts / advice appreciated.

Thanks.

Edit: thanks for the replies all. Very useful suggestions here.
