Munchkin Bag of Radioactive D6
We refuse to write a complex description for dice.
These are 6-siders, and there are six in the package. Three of them match the die in Munchkin Apocalypse. The other three do not. They are scary green and orange. They have the Munchkin head in place of the 1. Buy them. Kill monsters and take their stuff.
And if that's not enough, they come with four new Munchkin Apocalypse cards!
