In his review, Kevin got to try out the SafePal Cypher, a nifty metallic board made of stainless steel that helps protect your mnemonic phrase, also known as your seed phrase. This is a series of words that's used to create a unique recovery key for your crypto wallet. The Cypher comes with two stainless steel plates that you can easily assemble by hand to store a 12, 18, or 24-word phrase. The main purpose of steel wallets is to keep your seed phrase safe from physical damage and degradation.
When Kevin unboxed the Cypher, he found that it was user-friendly and came with a user manual, stickers, steel letter tiles, Allen keys, and extra screws. He was able to insert the letter tiles spelling out his seed phrase into the corresponding slots on the Cypher, which follows the BIP39 Mnemonic Phrase Standard - a list of 2048 English words that can be identified by their first four letters. The SafePal Cypher did a great job of protecting the seed phrase and he thinks it's a reliable and durable solution."
