The mark consists of two symmetrical, overlapped, interlocked diamond squares (or rhombuses with right angle) with one corner forming a loop. Each rhombus has 3 curved corners and the last corner being a loop. Starting from left to right, the first rhombus starts with a curved end (from left) and finished with the loop corner to the right end. The second rhombus is identical and superposed to the first rhombus, but with the reversed disposition. So, the second rhombus starts from the right with a curved end perfectly superposed and blended into the loop right end of the first rhombus,with the second rhombus finishing with a loop end perfectly superposed and perfectly blended into the left curved end of the first rhombus. At the top and bottom, the two-rhombus intersected into a V shape. Look another way, the image is made of 4 paper clips symmetrically disposed to form a diamond square (or rhombus with right angles) in the middle (inside), a circle at both left and right horizontal ends, and, vertically, a V on both the top and the bottom.
