Keeps coffee warm and seal does not leak.

Vacuum seal does not leak! These are my goto coffee and water tumblers. I have Parkinson's and it makes me Sir Drops a Lot. I love that the seals stay sealed. Both cups are full of water. One cup upright and the other upside down. No leaks onto the counter.

Best travel cup ever!

I absolutely love these travel cups! The black and white colors were ideal for my preferences. The vacuum seal keeps my drinks hot all day and the screw top makes the cups completely spill proof when the lid is closed. They hold 20oz of liquid and are dishwasher safe. The size is perfect to fit right in my hand and they fit in every cup holder I've tried.

Great Everyday Tumbler!

We picked up this 2 pk of MM 20oz Coffee Tumblers at Sam's Club. The stainless steel construction is sturdy and well made. The double walled design works great. Coffee stays hot and ice lasts for hours. The magnetic slide lid is a very special feature. It opens and closes very smoothly. The base fits in a standard cup holder in your vehicle. The exterior stays dry and cool to the touch, so no worries with holding. Cleanup is easy since the lid screws on and off and the slider pops off for easy cleaning. Solid value and Definitely recommended.
