The Cage is a variety of packaging in which the assembly of wooden boards occurs intermittently, and this makes such a packaging cheaper in comparison with the Case, due to the fact that a smaller amount of wood is used for the construction. The Cage is similar, as function and versatility, to the Case; the difference lies in the type of material that has to be packaged: indeed, such a container is mainly used when there is the possibility to fasten the contents, being it voluminous or heavy, to the bottom of the Cage.
