Our Dart candles are the perfect introduction to our range of fragrances. They are a gorgeous little votive size holding on average 60 grams of wax. Don't let the size fool you, they will burn for up to 20 hours for your enjoyment! How?!? Well the glass is a specially designed handblown borosilicate which means it's beautifully thin allowing a larger internal volume for its size. Normal candle glass is on average 4-5mm thick, ours is 2mm! PS. When the candle is finished, the glass is food grade - so pop it in the dishwasher and you can re-use as a food or drink glass!
