Fragrance
Typically, the fragrance of larger scented candles tend to last longer than smaller ones. For a gauge, a 100g candle should last for approximately 25 - 30 hours whereas a 300g one can last anywhere between 55 - 65 hours. To prolong its longevity, store it properly!
Colour
Similar to fragrance, scented candles may lose their colour if not stored properly.
To prevent this from occurring, keep your scented candles out of direct sunlight and store them in airtight containers.
