Hodlr Classic Edition (3-Pack)

Mark M.
Beautiful design and permanent security

This is a really elegant and clever design to securely store a seed phrase forever. I knew I wanted a steel solution, but the others I saw rely on inserting little metal letters or discs into a container, and if the container accidentally spills out and the letters are out of order, you’re completely out of luck.

Highest quality seed phrase storage

The only device on the market made from 316L quality steel

Very Happy

I bought 3 hodlr swiss and im so happy, all of 3 are perfect, the only problem is one automatic center punch that doesn t work, so I used another.

Great product.

Simple product with good instructions. Works like it should. Very happy with my purchase. The magnet on the bottom is a nice touch.
