A corner protector comprises two sheets of superposed material joined along two straight edges that meet at an angle of 135°. It is open along any other edge. The sheets are swingable relative to each other about the joined edges, whereby when the sheets are swung about the joined edges until the two edges are at a right angle to each other, a corner protector is produced which has three flat sides each of which meets the other two sides at a right angle. In another embodiment, the two superposed sheets of material each have five edges, the edges of the sheets being joined together along four sides but free from each other along a fifth side, a first and second side meeting each other at an angle of 135°, a second and third side meeting each other at an angle of 90°, and a third and fourth side meeting each other at an angle of 135°, whereby the corner protector has an axis of symmetry parallel to the first and fourth sides, thereby to provide mirror image halves of the protector on opposite sides of that axis, so that when one half is everted and inserted into the other half, a corner protector as first recited is produced.
