Kinder Surprise, also known as Kinder Egg or Kinder Surprise Egg, is a milk chocolate consisting of a chocolate egg surrounding a yellow plastic capsule with a small toy inside. Manufactured by the Italian company Ferrero since 1974, it was co-created by Michele Ferrero and William Salice, and is one of several candies sold under the Kinder brand. Kinder Surprise was originally created with children in mind, replicating an Italian Easter family tradition in which adults give children large chocolate eggs with toys inside. However, Kinder Surprise toys have become collectible for adults as well. Since 1974, 30 billion Kinder Surprise eggs have been sold worldwide.
