Interdepartmental memo

Interdepartmental memos are a method of communication between departments at the Ministry of Magic. They usually take the form of purple paper airplanes, with "Ministry of Magic" stamped along the side.

The Ministry used to employ owls for this purpose, but discontinued use because they left droppings everywhere.
