Something cheaper than these hardware wallet intresting
Hardware wallets are wallets but this is a seed phrase storage. That makes them different.
some of the item you had listed are stainless steel right &
some are titanium so which Which one is better?
Both are good to offer eight protection against fire.
Also I am curious to knew like resistant to fire like @Charles-Tim mentioned
But if the steel ones got rusty or get scratch
will that also effect them?
Store it in a good place that has no moisture to avoid corrosion.
