This papercraft is a Skull Valentines Candy Box, good for halloween, the papercraft is created by Ravensblight. "If you're particularly fond of someone, it's always a charming gesture to offer them a heart shaped box of chocolates. It doesn't even need to be Valentine's day. And this is the ideal box if your heart is a bit dark and spikey. Or if their heart is dark and spikey. Or if BOTH your hearts are dark and spikey."
