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 spill-proof 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.
