The mark consists of a line drawing of a circular, dome-shaped object, resembling a vented or perforated lid or cover, viewed at an angle to show its three-dimensional form. The top surface features a concentric arrangement of circular holes, with a triangular or arrowhead-shaped central element, possibly a grip or indicator. The body of the object includes tiered, ridged sides that taper outward toward the base. A small loop or tab is present on the side near the bottom, possibly for attachment or hanging.
