An improved shock-proof displaying and packing box adapted for a computer keyboard is a combination of a one-piece board folded into a topless case and a modified transparent dust cover for a keyboard which can be firmly engaged with the folded case serving as a top cover. The dust cover is mounted on top of a computer keyboard which is located in the unfolded board first and wrapped by the folded case then whereby the computer keyboard can be safely packed therein and clearly displayed for commercial purpose in a store. The one-piece board is made up of a front, rear, left and right side flap each of which has an extended top fold, and an inner fixing fold that are integrally connected but foldably separated respectively by a folding line; and four reinforcement flaps disposed at each corner of the board with each extending from a corner flap. On the periphery of each inner fixing fold are disposed a plurality of recessed cuts so as to form a number of engagement inserts therealong; the modified transparent cover is provided with a number of elongated grooves and protrusions on the edges thereof which are in engagement with the corresponding inserts and the recessed cuts on the periphery of each fold thereof so as to firmly fix the dust cover in place.
