You could put together a "set" yourself with cups and dice, but why? Just get a complete set, and this one from Front Porch is packaged up in a cute little die shaped box.

It'll pack and ship better than your janky set with Dixie cups in a masking taped ziploc bag, too.

(In case you have no idea how to play the game, wikipedia has the info:

I love this product. It's a great way to have a good time with family and friends.
