The mark consists of the word SANDBOX in lower case sans serif lettering centered in a partial rectangular shaped box that includes parallel straight left and right side lines and a connecting straight bottom line disposed between the two side lines and a wavy upper line that begins at the same level of the top of the left side line and gradually extending diagonally upward to the right forming a highest point above the N in SANDBOX and then slightly tapering lower to eventually meet at the same level of the right side line thus forming an overall outline of a sandbox.
