My favorite cups for hot or cold drinks are my Tervis Tumblers. I've been buying and using my cups for almost twenty years. They are made in America, and in case you have never heard of the Tervis brand, I want to tell you just how fabulous they are.
The cups come in many sizes and styles and are not only for use with cold drinks, where their insulated style will keep the plastic from sweating, but they will hold hot drinks as well. They can be put in the freezer and microwave and will stand up to dropping and much more. They are so sturdy and well-made that the company offers a lifetime guarantee for their products.
There is much to love about the Tervis drinkware and the biggest problem you may have is deciding on which theme, or design to choose.
