I absolutely love these! They are pricey but worth every dollar. They look like glass but aren’t! Perfect for my busy family. You can put some ice cubes and still have lots of room for your beverage. Best part it that they won’t shatter in a million pieces if dropped (which is great when you have pets or young kids around). Definitely recommend to anyone. Although they are stackable, they kinda suction together so we store they individually in the cupboard.
