Durability: Only as durable as cards can be.
Fun: If you have other Munchkin sets this is fun. Not a standalone game.
Educational: As educational as dice can be.
Munchkin Fairy Dust Dice have no special rules like a lot of the other Munchkin addons. They are just dice. If you have the Munchkin Dice Bag these dice are nice addictions to your growing Munchkin dice collection. They come with some Fairy Dust cards which are nice to add to the Fairy Dust deck. However the cards have separate rules if you do not have the Fairy Dust deck. In a nutshell you give a card to each player at the start of the game.
