If you are not sure of the height of your gravelight, the adjustable refills are the perfect solution for you. These are traditional refills which, thanks to their placement in a special sleeve, make it possible to adjust the refills to the candle. In addition, they have all the advantages of oil and paraffin refills – long burning time, bright flame and safe use. This is the ideal solution when you do not know how to fit the refill to the gravelight.
