Abstract
A moisture-proof, easily transportable case for writing or drawing boards is provided. In accordance with the invention, a case which protects the writing or drawing board during transportation from the manufacturer to the user, and also protects the contents of the case from water damage, is formed by a process which does not generate a significant amount of waste material. Corrugated plastic foil (5, 6) is inserted into opposed case side support (3, 3') that are extruded from plastic. Additionally, separating bars (8, 8') are provided on the inside of the side supports to define the space (2, 2') within which a writing or drawing board is kept.
