at the very worst, you could just keep the box sealed for the week until you get your new humi. keep it in a room around 70 degrees. the cigs should be fine.
or, you can buy some "oasis" material (that's what on the inside of humidifiers) and get some of it wet with distilled water, put it either in a bag or aluminum foil (to keep the cigs from getting wet, and put it in the box with them.
