This box comes with the box base, five finger boxes, and the finger detail pieces! You can place treats inside the fingers, like smarties, chapsticks, etc.! These boxes come size at approximately 4-1/4" x 3-1/2" x 1" and are compatible with both the 8x12 and 12x12 mats. The files are sizable so you can make them larger or smaller to fit your needs. You can find additional images and a full tutorial on my blog: http://jamielanedesigns.blogspot.com/2014/09/halloween-fingers.html
