Description:The key to a magic relighting candle， is the special material added， usually flakes of magnesium. Magnesium doesn't require too much heat to start burning， just 800 to 430 degrees. The magnesium flakes start burning when you blow out the candle and ignite the vaporised paraffin. When you blow out the candle， the magnesium flakes appear as tiny particles on the wick and the magic begins.100% Brand NewColor: As shown in the pics.Candle Size:about 6*0.43cm10 Pcs candles in a pack.
