The Happy Birthday box is for any birthday up to 99. Keep them around for emergency office celebrations or send one to a far away friend. On one side there is a place for a quick note, on the other is a place to place a candle. Mark out the parts of the digital number to expose the age of the recipient. Strike a match on the side, light the candle and sing Happy Birthday. Box includes 4 small red candles and 4 matches, just in case you can use it again.
