The MK III version of our popular case replaces the combination locks with latches that may be locked with your own locks The Case is designed for the display, storage, and light transport of hobby models and miniatures. This case is not recommended for heavy transport such as, for example, the unprotected checking as baggage within an airplane. This product is designed to work best with our Display Boards (4 included; more may be purchased separately) and Unit Trays. This case comes with 4 Display Boards and 1 Drawer. This case includes an acrylic face to allow visibility into the contents of the case while the case is closed. The acrylic face is removable for easy access to the case when opened. The top lid of the case also opens to provide even greater access to the contents when the case is opened. The drawer of the case may be removed to allow greater customization and arrangements of the contents.
