Contigo SnapSeal Byron Double-Wall Plastic Travel Mug, 16oz, Violet

The first design in the SnapSeal line has many of Contigo customers' favorite features, including a one-piece, leak-proof lid for quick cleaning and easy, one-handed operation to fit any active lifestyle. To use, consumers simply push up the "SnapSeal" tab, opening a reservoir to access the mug's contents. After drinking is complete, snap the "SnapSeal" tab down to seal the lid again. An audible "click" - thoughtfully integrated by the design team - assures users that the lid is sealed again, 100 percent leak-proof and ready for whatever the day has in store.
