From LSA International comes the Gio Line Tumbler XL - Set of 4. The glasses are handcrafted by master glassblowers who created the fluted impressions in the glass while they are still molten. Its edges are then cut and polished to achieve a smooth finish. Gio Line Tumbler XL - Set of 4 can be stacked inside each other and machine washed. Its generous size and shape are perfect for drinks as well as serving ice cream or dessert, for example. The glasses are machine washable.
