As long as you keep the wick trimmed and only burn them for 4-5 hours at a time:

Large Tumbler 300g candles last approximately 50-55 hours;

Small Tin 170g candles last approximately 30-35 hours;

Tealight candles last approximately 3-4 hours.

Before you trim your wick, make sure you have extinguished the flame, let the candle cool down and remove any wick debris.
We recommend always trimming your wick to approximately 5mm.

While paraffin wax is refined from crude oil, soy wax is made from soybeans. Compared to paraffin, soy wax burns cleaner with no petrol-carbon soot. Soy wax also burns slower than paraffin, so soy wax candles also last longer.

Once you begin to burn your candle, the crystals and dried flowers / herbs will sink down into the melted wax.

Our jars can be reused you just need to clean them out throughly and remove the wick.

At this time we do not offer refills.

Alternatively, once you have cleaned the jar you can reuse your candle jar as storage for office supplies like a pencil holder, craft accessories, or bath items, like cotton swabs, hair-ties, makeup brushes or a toothbrush holder.
Why not plant some succulents in them also!
