No birthday is fun without relighting candles. The specialty of these candles is that they get relighted automatically after you blow them off. This type of candles is also known as magic candles as they can relight them up on their own. All you have to do is light them once and after that even if you blow them off they can relight them up again. They are also available in bright colours. These are known to be perfect candles that you can sue on your birthday.
