These boxes are approximately 3" x 1-3/4" x 5/8" and hold the standard 1oz (29g) Tic Tac® container. The file comes with the box base, a lid, and the paper elements shown. The file is compatible with both the 8x12 and 12x12 mats. You can find additional images and a full tutorial on my blog: http://jamielanedesigns.blogspot.com/2014/11/tic-tac-boxes.html
