Happy Birthday Cake candles come in a pack of 20. 10 different colours per pack. We started making them for our Steiner Schools and they've become so popluar, we've added them to our range. they're approx. 16cm tall with a point on the end for easy cake insertion. You can sing happy birthday over and over again and hardly use any of the candle. You can rince them off in warm water and store them in a jar for the next birthday. New
