UMD: Containers designed to be used to transport materials via mail services, such as the U.S. Postal Service or other carriers. These containers typically consist of boxes, tubes, or envelopes that provide appropriate protection for fragile materials, insulation to preserve temperature sensitive materials (e.g., clinical samples), and/or special pockets to separate and facilitate the transportation of several objects simultaneously. Mailers are used in health care facilities to send and/or collect clinical (i.e., laboratory) samples, microscope slides, and other sensitive or fragile products. Mailers are available either for single use or reusable.
