This box is approximately 3" x 3" x 1-1/2" and fits the Birthday Cake Tealight. The box sides "explode" out when the lid lifts exposing the tealight cake. This box can be used on its own as well and is compatible with the 8x12 and 12x12 mats. You can find additional images and a full tutorial on my blog: http://jamielanedesigns.blogspot.com/2014/10/battery-operated-tealight-cakes.html

This item coordinates with the Birthday Cake Tealight.
