Kinder Surprise, also referred to as a Kinder Egg or, in the original Italian, Kinder Surprise (Kinder may be the German word for "children", sorpresa is Italian for "surprise"), is really a candy made by Italian company Ferrero and introduced by William Salice (1933-2016). Originally meant for children, it is also popular with adult collectors and it has the type of a chocolate egg containing a little toy, usually requiring assembly.
Each Kinder Surprise egg consists of a chocolate shell, a plastic container, the contents of said container, as well as an external foil wrap. The chocolate shell is shaped like a chicken's egg. It is only a couple of millimeters thick, and includes two layers: a milk chocolate layer on the outside, along with a candy layer inside. The shell is made of two identical halves, which are lightly fused together right before the egg is wrapped, to avoid the halves from coming apart underneath the light pressures expected during transportation.
During the egg's production, prior to the halves are fused together, the plastic capsule containing the toy is positioned inside. This capsule is made from thin, flexible plastic, and is often yolk-yellow. The capsule is made of two non-symmetrical, overlapping pieces: its bottom piece is almost as long as the whole capsule, and it has two ridges protruding along its outer rim; the very best piece is all about half as long as the whole capsule, and it has two corresponding ridges along its inner rim. Once the pieces are pushed together, the ridges interlock and do not break without manual manipulation. To split up the 2 pieces, it is often necessary to apply pressure to the interlocking region at its opposite ends, bending it and causing the ridges to separate inside so that the halves could be pulled apart. Once the capsule is opened it can be re-closed effortlessly by pushing the two pieces together again.
The plastic capsule provides the toy itself (either in a single piece or in several pieces requiring assembly) and a minimum of two pieces of paper. One paper lists the "choking hazard" warnings in multiple languages. Girls Pop The other paper shows assembly instructions for that toy along with a picture of the assembled toy (if applicable), and/or sign of toys belonging to the same line because the one contained in this particular particular capsule. Many capsules also include a small page of adhesive decals that may be put on the assembled toy after construction.
When the egg is assembled in the factory, it's covered with a skinny metal foil bearing the Kinder Surprise brand and various production details. The eggs are then sold, either individually or in a boxed set of 3 eggs, or perhaps in some cases in a tray of 24 eggs.
Assembly of the toys requires no additional tools, as the pieces will simply lock ("snap") together. Assembly rarely takes lots of easy steps. Most toys could be disassembled and reassembled freely, while several can't be disassembled without causing permanent damage. Over the years, Ferrero also have created a variety of no-assembly toys, whether more complex toys you can use immediately or simple character statuettes made from just one, pre-painted piece of hard plastic.
During the 2000s, Ferrero redesigned the Kinder Egg's internal plastic capsule. The new design is visually and functionally similar to that of the original capsule, however it now consists only of a single bit of plastic with a hinge on one side. The size and particular style of each half of the capsule have also been slightly altered accordingly.
