100% lead free crystal , CE/EU certified, Smooth rims, Elegant looks The glass for martini and some cocktails has a triangular bowl shape. This form has the opposite effect in comparison with the glasses for sparkling wines. It supports quicker releasing of bubbles from the drink, and, much more than any other glass, evolves the aroma of the drink around. This is the reason why just this glass is often used for serving cocktails and vermouths, such as Martini Dry decorated with an olive, Cinzano with lime skin or famous Cosmopolitan. Oftentimes, the glass shall be specially adapted prior to cocktail making.  For example, a moistened glass can be placed to the freezer for several hours to create a thin layer of ice on the surface of cup, or the rim of the glass shall be smeared with lemon and then sifted with sugar. A martini glass shall always be perfectly clean and polished, without any residue of water or detergents. Glasses are supplied in a gift packing.Not suitable for microwave.
