The exclusive, hand-dyed STOFF Nagel taper candles by Danish ester & erik have a long and tapered shape with a cone-shaped bottom to make them fit perfectly in the STOFF Nagel candle holders. The candles do not drip, are self-extinguishing and burn out slowly and elegantly so that no residues are left in your candle holders. The candles are made of pure paraffin wax, a pure mineral product cleansed of impure particles. Furthermore paraffin wax has the smallest carbon footprint and the least environmental impact of all waxes.
