This adorable gift bag is approximately 6-3/4" x 7" x 4" in the widest areas and is compatible with both the 12x12 and 8-1/2x12 mats! The file comes with a base box piece (cut two) and decorative panels (cut two) and the sides each have two holes so you can have two ribbon handles. This bag is great for gift giving or could even be used for large party favors or a purse!
