This file comes with a box base and box lid which is approximately 6-1/4" x 5" x 1-1/2" and the Thanks Coach circle with the sport ball design. You can use the pieces separately or together as shown! The file is compatible with both the 8x12 and 12x12 mats. You can find the tutorial on my blog here: http://jamielanedesigns.blogspot.com/2016/03/thanks-coach-boxes.html
