They're not casino dice but it doesn't matter because we don't use them in casinos or for playing.

Here's a quick review of Chessex d20 dice (bear in mind they're not the same as d6).

The dice can be used for 2 things in the context of Bitcoin:

• Generating entropy for the seed (eg. using Coldcard Wallet)
• Generating a passphrase using a diceware list

I'm not too worried about the fairness of the dice in the context of Bitcoin.

Dice rolling might be exploitable in a casino (3 - 8 bits of entropy) but not in the context of a 128-256 bit entropy (or even 64 bits - eg 4-6 word diceware passphrase).
With Coldcard you can keep rolling if you're worried about the fairness of the dice, use different dice each time you roll and it'll keep generating new seed.
