Purim Pyramids
It's customary on Purim to give gifts of food to friends, called mishloach manot in Hebrew (or shalach manos in Yiddish). On my quest to invent ever more complicated packaging each Purim, these boxes consist of a pyramidal enclosure held shut by a band, with the holiday message lasercut out of the band. This construction requires no glue, stapes, or adhesive at all. Both pieces for each box can be cut from a single letter-size sheet of card. And picking the brighest colored paper I could find made these extra festive.
