All I can say is this mug is a complete game changer to the coffee drinking world. Whoever came up with the design of tan and brown is a complete genius. I no longer have to worry if my coffee mug is clean because there’s no way for me to actually know if it is or isn’t. The etched design on the exterior of the mug makes gripping your hot beverage easier than ever. I specially love the contoured handle and how easily my hand can slide in and out. If you’re in the market for a cylindrical object to drink your coffee out of this is definitely it!
