The relighting effect makes the candle-blowing moment more fun, interactive and memorable, making them a great choice for birthdays, surprise parties, family gatherings and funny celebration moments. Simply insert the candles into your cake or dessert, light them, wait around 30 seconds, then blow them out to enjoy the relighting surprise. Use under adult supervision. Keep away from flammable materials, and make sure the candles are fully extinguished after use.
