Outlines of letters A-Z are located at the top and bottom of each card, allowing you to carefully trace each letter. Crypto Seed Bank is a one-of-a-kind design: The built-in letter stencils make it easier to control each stroke of the pen for neater engraving.

Crypto Seed Bank boxes now include engraving tips that are thinner, sharper and a higher grade of Tungsten than previously available. These pens don't use ink - the metal tips are sharp enough to leave a permanent, visible engraving in the stainless steel cards.

Each card is made of 304-grade stainless steel, which has a melting point of 1450°C (2642°F). Our stress test shows that etched letters will still be visible after being heated to 1300°C (2372°F). Most house fires will never exceed this temperature. Additionally, our cards are rust and water-proof.

Each card is water proof, rust proof, and corrosion proof. Making your seed phrase nearly indistrucible.

As thin as a normal credit card, Crypto Seed Bank is ideal for hiding in places that no one would ever look.

Each card has ⌀ 4 mm holes designed to be screwed through, in case you want to hide your Crypto Seed Bank in a creative spot.

Your unique recovery keys should last you a lifetime. Engrave them on stainless steel.
