Mix N Match Exploding Box File which also comes with round 3 tiered Cake. Lots of variations of box styles can be made by mixing the elements provided, so you are not stuck with just one design.
All the layering you need plus a choice of top layers from plain, filigree and the hexagon. I have designed this file so you can go any size up to a 5" (130mm) box if you were to cut it from A3 card. If cut from 12x12 card the max size is approx 3.8 " (97mm)
