From their announcement:
The Pathfinder Beginner Box includes four highly detailed prepainted plastic miniatures for use with the Pathfinder Roleplaying Game. The four heroes included in the set also appear as the four pre-generated characters in Paizo’s Pathfinder Roleplaying Game Beginner Box (released in October 2011) making this an ideal supplement for new gamers.
The Pathfinder Beginner Box fantasy miniatures set has an MSRP of $12.99. All figures are on 1-inch round bases and are fully compatible with the Pathfinder Roleplaying Game and other major fantasy RPG game systems.
