Reduce your carbon footprint without having to sacrifice your favorite coffee with a My-Kap reusable cap for K-cups. Traditionally K-cups cost anywhere from 25 to 50 cents apiece, which can become very pricey for avid coffee lovers. Save your old K-cups and see more green in the environment and your wallet with this three-piece set. Simply refill your K-cups with your favorite coffee or tea. You can even expect superior flavor with this system rather than trying Keurig"s reusable K-cups, which can cost up to 14 dollars apiece and do not produce the same quality cup of coffee as the K-cup itself. Storage is also made easy as the caps can be stored right in the turnstile you already own for your K-cups.
