Each side of Coinplate Alpha has dedicated letter and word spaces deeply engraved in metal. Using included automatic marking tool, mark your seed words, letter by letter. You only need to press it down on the right spaces to make a visible dent in the metal. Thanks to BIP39 seed phrase design, you only need to mark down first four letters of each words.
To make the process even easier, you will find permament marker pen included in the box. Using marker pen you can mark the seed phrase first and double check, before you make a dent in a metal plate.

You can easily remove all branding and logos. The logo on the front is just a sticker. This way you can hide your Coinplate in plain sight.
