This OXO Good Grips single serve Liquiseal travel mug is a solidly constructed mug that features three silicone seals to ensure it never leaks or spills regardless on where you take it. The mug can be used with most single serve coffee machines and will fit most cup holders. A soft grip makes the mug easy and comfortable to hold and it can be opened and resealed simply with one click of a button. The non-drip spout has been contoured for comfort and the 280ml capacity is a convenient for traveling, whether by car, public transport or on foot.
