Float martini glasses by Todd MacAllen and Stephanie Forsythe of Molo Design are carefully handcrafted by master glassblowers in the Czech Republic using the highest quality German borosilicate glass. The float martini glasses preserve the classic shape of the martini bowl while harmonizing beautifully with the aesthetics of the float barware. The martini glasses are completely inert and will never influence the subtleties of your favorite martini. Set of 2, 4 oz. The fritted martini glasses are identical to the clear martini glasses except they have been glazed with a borosilicate frit, which contains a luminous translucent finish. The fritted glassware is a delight to both see and touch.
