Really smart idea โ instead of writing your seed phrase on paper, you stamp it onto a titanium plate. That way, you donโt risk losing your crypto assets if thereโs a fire or flood. Titanium has a much higher melting point and better corrosion resistance than common materials like stainless steel or aluminum, and the plates in this kit are very well made. Theyโre thick too, about 2mm, and have a nice solid feel to them.This kit doesnโt just record your seed phrase directly. Instead, you stamp the index number of each word from the BIP39 wordlist, which you can later reference to recover the full phrase. Itโs a very clever idea that makes recording your seed phrase even easier. They include a copy of the BIP39 list with the kit, but you can also easily find it online, like on GitHub.Another thing I really like is the size โ the plate is designed to be the size of a credit card, so it fits perfectly into a wallet or any other discreet spot. It looks and feels like a thick, heavy-duty credit card, which is pretty much perfect.All in all, great concept and really well executed.

This is a great way to protect your seed phrase by stamping it onto titanium plates. The plates are thick, sturty and feel high quality. Overall solid product, well made.
