Fact! We love this snarky mug! Details: 20 oz stainless steel tall travel mug. Image is printed on both sides. Not dishwasher safe, though the print is able to withstand a dishwasher on the top rack, hand wash your cup to ensure a long lasting quality print. Not microwave safe, the cup is made of stainless steel, do NOT put in the microwave. Metal straw + plastic lid included.
