Libbey Z Stem Martini Glasses are very unique and lovely. The graceful stem sets them apart from traditional martini glasses. The Z Stem is so unusual. The stem is strong yet light, making a perfect vessel for many other types of drinks. They hold 9 ounces of your favorite drinks. They also were perfect for a fruit frappe or a light layered dessert. Libbey hit this gorgeous set, right out of the ball park. Sturdy, yet graceful, they are perfect for an outdoor dinner under the stars. Easy to clean too. I wash mine by hand, as I do all my glassware. Give these unusual and fun glasses a try!
