Museum display cases are usually one of the most expensive parts in museum interior design and furniture; museum display cases are very special and have a lot of limitations in the selection of used materials. Usually, even the micrometer environment in museum shelves and display cases should be valuable in the primary control of a collection (1). The protected manuscripts in museums are particularly vulnerable in terms of vulnerability and difficulty in maintaining. The mechanisms of damage and preventive protection of these works and their changes over time depend entirely on environmental conditions (2). Display cases, as a means of protection, protect the works by increasing the security of the objects and confining them in an appropriate, stable and secure environment (3 and 4). In general, four main groups of factors cause damage to the manuscripts: 1- Physical factors 2- Chemical factors 3- Biological factors 4- Unexpected factors (5), each of which imposes specific requirements in the design and manufacture of display cases for protection. Due to the specific circumstances of these works, these requirements need to be collected and formulated in a purposeful way for the design of the display cases. This article has attempted to clarify what features each display case must have in order to be stable and to protect a manuscript by reviewing specialized texts, authoritative articles, and library resources. Finally, an example of an appropriate design based on the stated conditions is examined
