The mark consists of four square tile shapes in a row, slightly overlapping and tilting at slightly different angles from one another, above the words "FOR LETTER OR WORDS" in black all caps font, with the first letter of each word (F, L, O and W) in a simple grey box. The four square tiles on the line above "FOR LETTER OR WORDS" spell the word "FLOW". The first square tile is teal, with a white "F"; the second tile is grey with a white "L"; the third tile is teal with a white "O"; and the fourth tile is grey, with a white "W". The four tiles also feature grey shadowing in their background.
