This card is 4-1/4" x 5.5" and comes with a small gift box!  The gift box is approximately 2-1/4" x 1-3/4" x 1-3/4" and folds flat if needed.  The file is compatible with both the 8x12 and 12x12 mats.  See more on my blog here: https://jamielanedesigns.blogspot.com/2017/12/holiday-cards-with-gift.html
