The mark consists of two heads of one snake, the one on the left is clear with one eye and mouth shut, the one on the right is black or unclear with a curvier shape and it's tongue out, both heads connecting at the base as one. Inside the container the snakes create, there reside some literal elements, an L, a 7, and a bold dash underneath a thin dash within the space between the L and the 7. when the dashes are seen as a part of the 7, the letter F is perceived facing in the direction of the L mentioned. At the part where the snake's heads close in on another, a horizontal zig zag is depicted linking them.
