Pictures just show the engraver and the plates I used. I wasn't brave enough to put a picture of my passphrase on the internet.
In the article I linked, they do mention that engraving isn't perfect, ex, difficult to distinguish some letters and numbers (ie. B and 8), but we don't have that issue with passphrases. Also, the way the 2048 wordlist works is to help avoid confusion - lower/ uppercase doesn't matter and only alphabet is there (ok you need numbers at the beginning, but this is easy to notice).
I recommend having the list open in alphabetical order to make sure you don't end up with something difficult to distinguish or use capital letters v small ones when difficulty arises hn, rv, lI ....there are a few so uppercase is generally safer.
ex
value vs valve. (I'm not sure if both words are on the list), I had no difficulty drawing V and U differently - lines vs curves, but who knows?
Lol, yeah the funny thing is I do have those 2 pictures. But I decided against even taking a picture of what it looks like now.
It's obvious if it is stolen, but I want to know if someone ever opened mine, then reassembled it.
I find a problem with the wing nut and washer method, someone could open it, take pictures and close it up without you even noticing, then wait for a great time to steal your crypto (or take all the time in the world to crack the 25th word/passphrase).
With zip ties and markings, it would be easy to open, but a pain in the ass to close and reassemble in the same way.
Maybe scratching or drawing something on the outside of the washers would be good cause chances are they won't notice before taking it apart. They would naturally line up a line. So you could just line up the prime numbers or something.
You could also intentionally screw up the order of the stack since they have numbers anyway (not 1,2,3, all same side up). Just store your order in email and check when you are worried for whatever reason.
That's good, unique tape is best, in case, they have the chase to come back after ordering it on Amazon.
Crypto key stack is actually where I got my idea from. I just thought buying 1$ steel plates was cheaper...and less suspicious if people are checking out my mail. Building a deck, eh? Writing your name on your tools, eh?
I think the more measures you take the better. Sadly, chances are if it gets compromised it is someone you know and trust.
When I worked in IT, often it would be relatives who were scammed into thinking they were helping along with the occasional bad apple.

I was just being funny. I hope you would never.

You can buy stickers that deteriorate if broken, like warranty void if removed. In fact some of the commercial options use this.

The home printable paper wallets also use stickers you can purchase.
