The series was started approximately very early, assumed to be 1999, during the start of the Pokémon franchise in Europe and discontinued in 2011. The line only saw distribution in Europe and Switzerland. The Containers themselves were shaped like the iconic Pokéballs, originally featuring designs matching the different kind of Pokéballs available in the games, later featured mostly different, individual designs and patterns. Included in each ball was a random figurine from a specific assortment or set, which consisted of six to seven different featured Pokémon. Those were issued in no consistent cycle, nearly every year, in later cases even two sets per year. Some releases have names assigned to them, some do not. Also included was candy, which changed in shape and consistency through the years. Starting with the second 2006 release there was also a sheet of stickers included in each ball, which depicted every Pokémon found in the release.
