This box requires no tape!  You just fold it and the sides will curve up and fasten into the two side flaps.  The base is approx 3" square and the sides are approx 1" high.  Fill the box with candy or another small gift.  To jazz the box up, just add a sign or other doo-dad to the top tab with some wire works, a pipe cleaner or other temporary fastener (you'll have to remove your doo-dad before opening the box).
