These double wall insulated glasses are the best! I love the fact that they are completely microwavable and freezer safe. I also like the wraparound contour feature that provides a natural aesthetic grip. These type of glasses are very unique, elegant, stylish, lightweight and more durable than common glass. I would absolutely recommend this product because it does not leave water rings on the table nor leave your hands wet from condensation on the outside. No more sweaty glasses in our house that's for sure!
