LOL! No doubt!

Used safe. Go for the burglar rating. You can always increase the fire rating by building an enclosure around it.

What I did, years ago...

^^^ Yep... fireproof enclosure of Hardie backer board, etc. ... simple outta sight & outta mind for just docs & stuff. Isn't that sorta the stuff inside safes .25 = 30 min, .5 = 1 hr.

Couple of inches thick should work :D

I went through the same thing and after digging around a bunch, I decided to buy home safe from Liberty. It’s solid, has decent fire protection, and the lock doesn’t feel cheap like some of the ones I saw at the big box stores. Bolted it down in a closet, and now I’ve got peace of mind storing passports, backup drives, and random paperwork I don’t want floating around.
