RIVERS Plastic Wall Mug, Bar Solid, Black

This tumbler is perfect for both indoor and outdoor use. It's microwave-safe, so you can use it to warm up cold coffee, hot milk, soup, and more. The double-walled design makes it less likely to condense, so it's perfect for adding plenty of ice to enjoy a cold drink in the summer. You can also use it with a straw by inserting it into the large opening.
