The Japanese Puzzle Boxes listed below vary in size from 6 Sun to 9 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 7 Sun sized box is 1.2 inches multiplied by 7 or approximately 8.4 inches in length of the Puzzle Box.
