One of those boxes of nuts and lollies and stuff that you get for Christmas. They're divided into segments, with a different treat in each segment. They are usually divided into 3rds, quaters, or 6ths if you're lucky. These are all fractions, hence FRAC pack.
A: Hey! What did you get for Christmas?
B: A frac pack.

A: Mintage! What's in it?
B: Lollies.
