A type of retail plastic casing that protects expensive electrical gadgets. It is usually impossible to open with your hands, and very difficult to open using any other type of sharp device. The edges are usually completely sealed with no obvious ways of opening it.

The new USB memory chip came in impossiplastic casing.
