Trim the candle wick to 5-8cm each time. Please store candles in a cool, dry place and avoid direct exposure to the sun. Excessive temperature and light will cause the fragrance to diffuse excessively. Depending on the season, the wax may sweat or crack. This is normal and will return to normal after the first burning.
