The Secret Puzzle Boxes listed below vary in size from 4 Sun to 5 Sun. Please remember that Sun is a Japanese form of measurement. Each Sun is approximately 1.2 inches in Puzzle Box length. In other words, a 4 Sun sized box is 1.2 inches multiplied by 4 or approximately 4.8 inches in length of the Puzzle Box.
