Amazing quality

The HODLR disks feels amazing, much more solid and high-end than I imagined. Incredible product which is worthy of my BTC private keys.


Hodlr Classic Edition


Nice and heavy, great product.

Top Produkt

Ich bin begeistert vom HODLR. Sehr schön verarbeitet und verpackt alles was nötig ist, ist dabei. Aus ökologischer Sicht frage ich mich ob Kunden die bereits einen HODLR haben, nur den HODLR bestellen können ohne Werkzeug etc. für einen günstigeren Preis? Ansonsten empfehle ich das Produkt gerne weiter.

Hodlr 3 disk set look great!

The 3 set holdr that I purchased is of an very high quality.
The disk are from heavy material and the way of marking your word frase is one that’s worked out very fine with me. The manual description is very good and the packaging looks great! It Would be greater if a holdr disk good contain an six or 7 character word. This it good be possible to have on disk for your 24 words. Overall on of the best there is out there.
