Review on Shepherd SERENGETI Stainless Insulated Tumbler by Mark Jefferson

I bought this mug as a gift. The Gifted asks for this exact cup size (I prefer a larger cup size). The drawing of the cat was a wonderful surprise for her (she is a cat lady). The gasket on the lid keeps liquids cold and seals better than some of my famous mugs. The seal is so tight that it is difficult to remove or replace the lid without opening the drinking slot to let air in or out. I would feel comfortable adding these mugs to my "set" if I need a replacement.
