These green dice have black inked numbers. But whether your DM has the lights on, or has the group in the dark for ambiance, you will still be able to read the numbers with these glow in the dark dice.
This 7 piece RPG dice set comes with a d20, d12, two d10s (single and double digit), d8, d6, and a d4.
They may be novelty dice, but what else can you say, but that they are cool. Right? Just the thing for creating a great collection. And dark vision is not needed to keep playing the game when the power goes out with these dice. Something you just have to have.
