This attractive mug is made from a tough, shatterproof material to prevent accidental breakage. The liquid consumption is easily measured by the marked gradations and the mug is supplied with a choice of lids. The spout lid helps with drinking and the recessed lid avoids splashes. All of the interchangeable lids range below also fit the mug. The mug is dishwasher safe and microwaveable, but the lids should be washed by hand.
