I know you are thinking "Another box card?" well I love these and will definitely be making more! The amazing thing is that they fold flat and fit into an A2 size envelope, so much pop for that size. This is a cut file from SVG Cuts.
So check out that sentiment on the back...it is perfect for this don't you think? It is from the Music stamp set from My Craft Spot. If you know anyone that loves music you have to get this stamp set!
