Keeps drinks hot and lid is leak proof!

The members mark 2 pack coffee tumblers in tan and brown have quickly become my favorite travel mugs. The colors are attractive, neutral and stylish and I especially like that you can mix & match the lids to the cups. The lid design is my favorite part. It pours the coffee smoothly and doesn't spill a drop when it's fully closed. The material is comfortable to grip and doesn't slip when I pick the tumbler up. My coffee stays hot and my iced tea stays cold! Great product.

Great, quality tumbler set

These adorable 20 ounce travel coffee tumblers are good quality. I love that they come in a variety of colors. They are well made, stainless steel, top rack dishwasher safe, and have a max fill line printed inside so you don't over fill your cup. I also like that the closer tab on the top is magnetic and easily comes off, as does the the tab on the inside cover, for a more thorough cleaning. I think they would be perfect for hot or cold coffee.

Even when on its side these tumblers do not leak!

These tumblers do not leak even when turned completely on their side, even when turned completely upside down! The outside of the tumblers do not get hot or warm at all and stay comfortable to hold while the inside stays hot. The lid screws on and has a magnetic sliding tab that closes to keep the area that you drink from closed when not using. This magnetic sliding tab creates a vacuum like seal and really keeps your drink hot, you can hear it when you open the slide letting the air in. The colors are super cute and stand out from others. The shape allows you to grip the tumbler securely. The lid comes apart so you can thoroughly clean it so no hidden or hard to reach mold. To top it off this tumbler keeps my drinks hot all day.
