About this item
- ❰BUILT TO LAST❱ Made of 304-grade stainless steel, Crypto Seed Bank (CSB) is the perfect accessory for your cold wallet crypto seed phrase. CSB metal plates are waterproof, rustproof, and shockproof. Tested with a blowtorch, CSB can withstand red-hot temperatures up to 1450ºC (2642ºF), ensuring your engraved seed phrase can survive a house fire. Store your bitcoin seed wallet recovery key on CSB to help prevent the loss of your data in the event of a house fire, flood, or extreme shock.
- ❰CLEAR LETTERING❱ We’ve made it easier for all Hodlers to legibly engrave their crypto seed phrases by introducing a design which features integrated letter stencils. Etching your 12, 18, or 24-word seed phrase onto each of the crypto steel metal plates with the help of letter stencils is much easier than engraving freehand.
- ❰HIGH-GRADE TUNGSTEN❱ As of July 2022, CSB features significantly sharper and more durable tungsten tips than previous iterations of the product. Rest assured that you’ll be able to engrave multiple cold wallet crypto seed phrases without the tungsten tip becoming dull.
- ❰SLIM DESIGN❱ At just 0.7 mm (0.027 inches) thick, CSB is one of the thinnest crypto seed phrase storage options on the market. Our design makes it easy to hide and store your hardware seed wallet recovery phrase.
- ❰ENGRAVING TECHNIQUE❱ The process of engraving with letter stencils into the crypto steel plates can take 30 minutes or longer per card and requires moderate strength in both hands. However, you do not need to apply much pressure to successfully engrave. For best results, lightly trace the same letter repeatedly - Don't press down with all of your strength!

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
