AQUAPHILE Insulated Tumbler with Leak-proof Lid, 40 oz Insulated Stainless Steel Coffee Mug with Handle, Travel Coffee Mug，Light Blue

Bought it for my grandmother after she noticed/liked the 30oz. I bought for myself and from its color to its capacity to its sturdiness to how long it keeps drinks cold, she *loves* hers. A cup of iced tea can last almost a week from how much it holds and remains as cold as the day it was made. The base is even sturdier than it looks and the screw top adds an extra sense of security from spills in the event it gets accidentally knocked over on the table or refrigerator, (fortunately neither has yet to happen) and it naturally comes in handy for a trip in summer and of course, keeping coffee hot at home or on winter trips. The straw options are also nice and she prefers the clear plastic one. Overall, it's a very good all-around/anytime gift that immediately feels like you always had it and should've bought it sooner.
