We customized solid, polished crystal block decanters of exceptional weight and transparency to house intense perfume oil formulas in their primal composition. Why are they limited editions? Well, because their raw materials are not always available, following global market fluctuations. Powerful, they diffuse using a custom, single, extra thick 7 mm natural reed. With their concentrated perfume oil formulas, they are also an exquisite gift option for perfume lovers.
