The exclusive, hand-colored STOFF 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. The cotton wicks are made of 100% cotton, which has a lower impact on the indoor-climate than traditional wicks, as fewer particles are released.
