Carafe can be used with the included flexible straw, sipped directly from the lip or used as a pitcher with built in spout. Dishwasher Safe – These bedside thermal water bottles are dishwasher safe and are hassle-free and easy to clean. Cleaning these 32 oz water pitchers with a standard household cleaner after each use will allow you to use the cup multiple times in a clean safe manner. NOT for use in commercial dishwashers.
