These dice are very small tiny dice. They are 10mm cubes, please see the penny in the photos for scale.
These dice have become very popular for Disney's new Lorcana card game!
These dice have the sides: +1, +2, +3, -1, -2 & -3
You can use two of them to create a standard looking +1/+1 or -1/-1 counter or just use one as an indicator. You do you.
