This box is approximately 4" x 3-1/4" x 1-1/4" and features a lid that folds over the front of the box. The box comes with the box base, a clear window mat, and the mats. 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/2014/08/more-boxes.html
