I LOVE this tumbler. I'm extremely picky, but finally found the perfect hot-beverage tumbler for my daily morning coffee needs. I prefer to sip my coffee slowly so I needed something to keep it hot for a few hours at least. I love that this tumblr is leak-proof, because I can literally throw it into my bag, even upside-down, and not worry about it. Additionally, all pieces are dishwasher safe, AND it fits under the Keurig machine. Completely satisfied; I bought 3.

high quality tumbler
I enjoy every sip of hot tea from my thermos. It keeps high temperature for a long time. I am really satisfied with the thermos, it doesn’t leak like other cups that I had. It is easy to clean compared to more complicated lids. I highly recommend it. It’s well made, easy to clean, durable and comfortable to hold.
