The RealCup™ brand is in no way affiliated with Keurig Inc. or K-Cup®. In fact, they're our biggest competitor (really). Our RealCup™ single serve cups, however, are designed to work specifically in Keurig brewing machines... so if you have one, perfect! You'll at long last be able to enjoy an authentic cup of RealCup™ brand coffee or tea. That's the real truth!
