Post-it-Lamp

You can have the recepient or yourself, of this gift make a functional lamp out of the packaging material itself. "Lamp components come neatly packed into a postal tube. Surprise a friend with a unique gift: first you write the address on the tube, then choose the nicest stamps, and hop! On reception, no two lamps are the same! Different stamps, addresses, the lamp becomes a unique object." So I wonder what happens if the tube gets bent / cracked in the mail? Does the esteemed post master general buy you a new lamp?
