These halloween characters are approximately 5-1/2" x 3-3/4" x 2-1/4 when assembled. The top box (head) is 2-1/2" x 3" x 2" and the bottom box (body) is 2-3/4" x 3-1/2" x 2-1/4" and each can be used to hold goodies &/or surprises! In the file you will receive the two boxes for each character and all of the paper pieces needed to build the image shown in the image. These files are compatible with both the 8x12 and 12x12 mats. You can find additional images and a full tutorial on my blog: http://jamielanedesigns.blogspot.com/2015/10/3d-halloween-characters.html
