For both the Franci vase and the lantern, the shape is cut from a block of glass and cut and polished by hand to create these dazzling crystal objects. A special feature of the excellent quality of the crystal is that the natural lustre and transparency are retained despite the thick glass thickness. Only clean crystal glass with warm water, a little washing-up liquid and a soft cloth. Under no circumstances should you use cleaning agents that contain alcohol or are corrosive.
