Takeya's Traveler mug makes on-the-go coffee a breeze. Double-wall vacuum insulation maintains hot temperatures for up to 12 hours. The Flip-Lock lid provides a leakproof seal, easily opened and closed one-handed. A unique loop handle ensures easy carrying, while the built-in silicone coaster allows for quiet set-down. Constructed from 18/8 food-grade stainless steel, this mug resists flavor transfer and fits most cupholders.
