The mark consists of the stylized capital letters B, S, and M arranged diagonally within a rectangular frame. The letter B appears in light blue on the left side, the letter S appears in gray in the upper right area, and the letter M appears in black in the lower right area. Surrounding the letters are three nested rectangular borders: the innermost border is green, the middle border is red, and the outermost border is blue. A small white square outlined in black is positioned above the letters and contains three concentric black circles with a filled black center. Another small white square outlined in black is positioned below the letters and divided vertically into two sections: the left section is blank, and the right section contains several short, evenly spaced, black horizontal lines. The overall background of the design is white.
