This file comes with two different box bases so you can make a tall box, short box or both! The tall box comes sized to create a finished project of approximately 7" x 2-3/4" x 2-3/4". The short box comes sized to create a finished project of approximately 5" x 2-3/4" x 2-3/4". These boxes are perfect for holding chocolate candies, gifts, even homemade goodies! The file is compatible with both the 8x12 and 12x12 mats and can be made larger with the Cameo or smaller to fit your needs! The file has two box bases, they both use the same box top and the same box bottom. See more images and a full tutorial on my blog! https://jamielanedesigns.blogspot.com/2019/02/valentine-bags.html
