Designed for great taste, this Mug is made of 18/8 Stainless Steel with a quality, ceramic coating on the inside to protect beverages from metallic taste and smell. The ceramic lining is easy to clean, and doesn’t absorb any flavors over time. Use it for coffee, tea, or even a hot toddy, knowing each sip will taste just how it should—refill after refill.  Colors change frequently at RTIC please call to verify the color is still available.  We do not stock RTIC the delivery time is 4-5 days.
