This is a Twobert (a cube designed to be played by 2 or 4 players) containing some of the best common cards from all of Magic's history. It's based on the Pauper Cube, https://cubecobra.com/cube/overview/thepaupercube.
There are 180 cards, which divides into 12 packs of 15 cards.

Why make a smaller version of the Pauper Cube (which has 419 cards)?

1. It's easier to shuffle
2. It costs less money
3. When drafting with two people, I've found that it's better to have a more versatile and consistent base of cards. You don't want to get stuck with a bunch of gold cards in colors you can't use, or cards that are only good in particular archetypes, for example. Thus, I've pared down the larger Pauper Cube to this Twobert.
