Abstract: A storage container with locking lid and wall mounting arrangement for multiple containers is disclosed. The top left and right edges of the container have first extensions substantially along their length and an arctuate extension on each of them. The left and right rear vertical edges of the container have second extensions. A lid has rolled edges on its left and right sides and there is a hole through each of the rolled edges. As the lid is attached to the box by sliding its rolled edges over the first extensions, the arctuate extensions slightly deform the rolled edges until the box is fully closed and the arctuate extensions then enter the holes to lock the lid to the container. When the lid is removed from the container it is attached to its rear by sliding the rolled edges of the lid over the second extensions.
