The mark consists of a design element and a literal element. The literal element of the mark is 2 words: "Rounded Pebble". The text does not use a specified font but both words are capitalised. The position of the words can change relative to the design element but the reading sequence is retained as "Rounded" first, then "Pebble". The design element of the mark is comprised of six separate shapes that collectively appear as a distorted sphere with a gradual protrusion to the lower right side - to resemble the 2-dimensional shape of a rounded pebble. Each shape is positioned in a vertical stack as a horizontal layer. Each internal side of each of the six shapes conforms to the adjacent shapes' contour(s), such that each layer appears to loosely fit with the facing side of the adjacent shape. The gaps between each of the six shapes is quite narrow and creates a clear impression that each of the six shapes is associated with the adjacent shape(s). The gaps between the six shapes are not assigned a color and will appear as the same color and pattern as the background. The outer sides of the six shapes are collectively contoured to conform inside the imaginary rounded-pebble shape of a distorted sphere described above. The overall impression of the six shapes is of a rounded pebble with flowing-water-like gaps between the six separate shapes. The color of the mark, including black or white, is chosen on a usage basis to ensure strong contrast with any background.
