All Michelangelo Masterpiece glasses are made using an innovative new glass material called Sparx. Sparx was developed by Luigi and is exclusive to their glasses alone. Sparx Ultra Clear Glass is stronger and more durabel than ordinary glass plus more clear and transparent allowing for a better drinking experience. Sparx Ultra Clear Glass is as eco friendly as glass can be; it is completely lead and heavy metal free. All Michelangelo Masterpiece items have drawn seamless stems, laser cut fine rims, and come in a photographic giftbox of four. This glass is ideal for white wines.
