Multipurpose EM grid box offering secure storage with integrated documentation. The tree-shaped grid storage cavity ensures that tweezers come into contact only with the edge of grids, virtually eliminating the chances of damage. The base of the box is made of white plastic to provide good contrast, and the lid is made from clear plastic. A windowed sliding cover beneath the lid helps to minimize the chance of grids being lost or damaged, by only exposing four grids at a time. In addition, a record card slots into the back of the box, assisting accurate and reliable record keeping.
