Our Happy Birthday Candles Card offers many advantages over a cake with birthday candles. For example, you can write a message in a birthday card. There’s no dripping of hot wax or setting off smoke alarms. There’s no awkward “we forgot to bring a knife” moment. A birthday card will also last forever. But, maybe, best of all, the number of candles on the card doesn’t give away the age of the person who it’s for.
