The Quencher H2.O FlowState™ cup has a seal that prevents accidental spills when the cup is in an upright position. However, due to the lid's straw hole and its design, the Stanley Quencher mug is NOT completely leak-proof. We do not recommend placing it in a bag or backpack if there is a risk of the mug tipping over. The manufacturer does not guarantee the leak-proofness of the Quencher H2.O FlowState™ Tumbler.The mug is dishwasher safe, but to maintain its stylish appearance, we recommend hand washing it using a soft sponge, mild detergent, and a straw brush set.
