I use this lamp with water and fragrance oil. Who really wants to bring fragrance wax to melt, can take an ordinary fragrance candle from his Aluminiumülle and remove the wick with a metal part and place it on the lamp above. Special Tarts must not buy.
However, a Lieferzheit 10 days for Airmail from England is an impertinence. I have noted in the supplier evaluation, so there is no penalty.
