Kinder Surprise originated in 1974 in Italy. The manufacturer is Ferrero.
They are not suitable for children under the age of 3 due to the small parts which may be ingested or inhaled. They are banned in the U.S. where they can only be filled with small candies.
A relatively new innovation, triggered by the advent of the Internet, is the introduction of 'Internet surprises'. Accompanying the toy is a small slip containing a 'Magicode'. For further details, or to utilise a Magicode, consult the Magic Kinder Website.
