The Big Bang Theory Mystery Minis
This might be the first collectible figure line based on The Big Bang Theory that's worth collecting. The Big Bang Theory Mystery Minis, from Funko, are a blind box figure line. The 2.5" figures include 7 Little Sheldon variants, 2 of each of Leonard, Howard, and Raj and 1 of each of Penny, Bernadette, and Amy.
Look to get your blind box nerdiness on beginning August 8th 2013.
