Proxy container

Proxy container is an item in the Factorio data set categorized as a special/other item with a stack size of 10; beyond its name and category, no additional functional data is provided in the structural description. As a special-category item it is not a standard crafting component or building and is likely used by the game or mods for nonstandard purposes, but the available metadata only confirms its identity, type, category, and stack size.
