This box is approximately 5" x 5" x 1-3/4" and the file comes with the base box pieces (4), the lid pieces (4), and two ruffled heart cuts, and the doily scallop heart. The file is compatible with both the 8x12 and 12x12 mats and can be made larger in both formats! You can find additional boxes, the full tutorial, and more on my blog! https://jamielanedesigns.blogspot.com/2014/02/feeling-love.html
