Who's going to suspect a metal plate with "random" holes to hold your money?
People who know about bitcoin and seed phrase backup solution probably know about similar system like this.
This is not the first time I see stainless seed plates that use combination of letters and number that combine to seed words, but I never like it.
I don't think this is bad in any way but I think it's inferior compared to Steel Washer backup, maybe because you need to have the full list of seed words.
Positive side is that it's probably easier do stamp dots on stainless seed plate (or paper).
