This travel mug has a beautiful 3D artwork of dogs and cats. If you have a pet or know a family or friend that has a pet, this tumbler makes a great gift! The Serengeti tumbler comes with standard BPA Free Spill proof lid that has a slider to open and close. The lids use a high quality silicone-seal to keep from spilling. These Tumblers have a No Sweat Design to keep hands dry and safe from extreme hot or cold. The double wall insulated tumblers are made of solid construction with 18/8 stainless steel body, so your drink keeps its temperature. The tumblers have a durable smooth coat of paint that won't fade, or crack through extended use and the shape of the tumbler is especially designed for easy grip. A special 3D German printing technology is used with a high gloss finish. You can feel the dogs and cats slightly raised to have the 3D feel. For best quality and durability, we recommend hand washing only for your new tumbler. - This item is NOT microwave safe.
