Double-walled cups are not only stylish, but they are also typically more durable than their single-wall counterparts. Many of these cups are made from borosilicate glass, which is designed to withstand temperature extremes without shattering. This durability makes them ideal for both hot beverages, like lattes, and cold drinks, such as iced coffee or smoothies. Some double-walled cups also come with lids, making them perfect for on-the-go beverages without the risk of spills or burns.
