If you're looking for much more durable solutions, you can consider a piece of sheet metal, letter punches and a hammer.
Thanks for the tip. I've thought that printed text from an inkjet paper would fade over time. But based on your experience, it looks like it'll last a lifetime. I believe that glossy paper tends last more than regular/standard paper used for everyday printing. This, combined with lamination could make the BTC paper wallet last for a very long time.
I've heard about the steel wallets, but they're much more expensive than printing your own wallet at home. The "CryptoSteel" metal wallet is the most expensive one yet. But, I'd say it's worth every penny for securing your BTC funds for a lifetime. The other one called the "ColdTi" is made of Titanium at a much more affordable price than the "CryptoSteel". In times of turmoil (like the ones we're facing today) metal wallets are so much better than paper wallets because they're resistant to almost thing you could imagine.
As a last resort, one could always make a "tattoo" of Bitcoin keypairs that will always be with you wherever you go. It's painful, but at least your Bitcoin will be safe as long as you're alive in the real world.
You can find some solutions like that on stationary store, and with this the only thing that will destroy your paper is fire or if someone stoles
you could go on a printing place too, but you have to trust on another person, so it's safer to do what I said above
Thanks. But, I'd prefer to laminate the wallet myself than using a third-party service for privacy reasons. There are many cheap laminators out there on retail stores, so I could just print the wallet on standard paper and laminate it for safekeeping. I'm sure it'll last a lifetime. The only downside is that it won't be resistant against fires. But I wouldn't worry about this since the wallet itself will be contained in a fireproof safe. It'll be buried someplace on the ground so I expect it to last for many generations.
And then after that, you can protect your paper with some tricks to make them water-resistant.
Read this "3 Ways To WaterProof Paper"
I'm sure those steps can help protect your Paper wallet to any damages except for fire.
I would like to add the 2nd method from this "Coating Paper With Chemicals"
it seems it can help to make the paper fire proof.
A combination of Wax and the chemical might help to protect the paper on both fire and water.
I did not know that. Thanks for sharing. The wax and chemical combination for protecting the paper wallet against fire and water is genius. If it works as intended, this could be a cheaper alternative to existing metal wallets like the "CryptoSteel" and the "ColdTi". I'll be sure to try this before laminating the paper itself for added protection.
