An elongated flat plastic box hinged along one side is provided with a pair of latches spaced along the opposite side. The male part of the latch is connected to an actuating tab formed in the top at one end and in the bottom at the opposite end of the elongated box. The female part of the latch is formed in the opposite part of the box in mating relationship with the male portion of the latch. This alternating arrangement allows the normal twisting action of left and right hands attempting to open the box, to disengage the latches and simultaneously open the box for exposure of the contents by simply applying pressure to the actuating tabs. The entire box, including the latches, is molded in a single operation.
