Whether you like them plain or with bold colors and stripes, it is hard to beat foam cups when it comes to keeping your beverage warm - or cold, for that matter. When you use a foam cup, you wont need one of those cute little paper jackets like they put around those $4 cups of coffee at a well-known coffee house. Whatever your choice, match them up with the right lids. Remember you can choose a flat or sip type lid to fit on your selected foam cup, depending on your application.
