thebitcoinhole.com launched a new section on our website: "Seed Backup". We compare different seed phrase metal backup solutions, feature by feature. You can filter, sort and compare.
We have plans to add more solutions, this is just the start.
Nice work.
You are working quickly following my suggestions
Good source of information for seed backup is
Jameson Lopp with his website and github page.
He already has a page with detailed reviews, rating, prices and he personally stress tested this product with extreme heat, acid, etc.
You don't have to add all products listed there right away, but it would be good to check them out, and I am sure there are more of them he didn't test.
I had few more sources bookmarked, but I have to find them, and you can also add simple Stainless Seed washers that work great for this purpose and they are cheap.
