Theyre the boxes for screamingly funny, hilariously awful, but scarily plausible products that dont really exist. The photography, typography and layout of these boxes are perfect. I mean, they look exactly like the cheesiest products youd buy from TV infomercials. Anyway, the point is that you put peoples real presents inside the empty Prank Pack boxes. Then, when they unwrap their gifts, you get that delicious moment of watching their faces as they struggle to be tactful. They think youve just given them the all-time turkey of presents. Once they figure out that its just a satirical prank, theres even more laughter and then gratitude for the much more thoughtful present youve stashed inside.
