Coldcard can add randomness when generating a Private Key by rolling dice.

I got my hands on some precision dice to ensure that the odds of rolling a certain side of the dice is as close to 1/6 as possbile.

Features of precision dice:

🎲 Filled with resin of the same weight to prevent any imbalance.

🎲 Edges are smoothed out so they don't wear unevenly.

🎲 Transparent, making it obvious that there are no weights inside.
