The mark consists of a green circle surrounding all literal and design elements. At the center of the circle is the literal element "One Step Sponge" appearing in purple. Immediately above the "One Step Sponge" literal element is a green check mark within a green semi-circular shape. Immediately below the "One Step Sponge" literal element is a pair of black shoe step forms within a green semi-circular shape. Located between the center design elements and the outside green circle is the literal element "Control Foot Traffic Contamination" appearing in purple read clock-wise starting near the bottom of the circle. A purple star appears both before and after the "Control Foot Traffic Contamination" literal element. The two purple stars straddle the black shoe step forms in the interior of the green circle at the bottom. The white in the drawing represents background and/or transparent areas and is not part of the mark.
