A slide box is a small storage container used to protect microscope slides from damage and contamination during storage and transportation. It is typically made of plastic or metal and has a hinged or removable lid. The inside of the box is divided into compartments that hold individual slides securely in place, often using foam or grooves.

Slide boxes come in different sizes and can hold a varying number of slides, typically ranging from 25 to 100 slides. They are commonly used in research and clinical laboratories, pathology departments, and educational institutions for the safe storage and transportation of microscope slides, which are used for a variety of applications, including histology, cytology, and microbiology.
