480ml Glass Mug Sets(2 Pack), 16oz Flat Bottom Glass Coffee Mugs, Heat-resistant, Large Clear Glass cup with handle for Beverages, Tea, Cappuccino, Latte, Espresso, Juice...

Nobody seems to mention this, which is the main reason I selected this product: unlike other mugs that have a ridge around the bottom, the relatively flat bottom on these mugs is much better at conducting the heat from my coffee warmer hotplate, so I don't need to keep it covered any more and it maintains a constant temperature. The perfect volume, light weight and nicely shaped handle are additional benefits. I plan to buy more.

These are great. Hot coffee stays hot on the warmer! ! ! Why manufactures of mugs that make claims of such don’t get this. I have seen so many mugs, that claim “ fluted bottom “ “ flat bottom “ and they just are not! This just works!

Looked for flat bottom cups for ages, even tried to grind raised ring bottoms so mugs would sit in contact with warmer. Attractive, useful, & nice size.

These glass mugs were replacements for ones I had for a long time. They are not as solid as the others but as I said above they are good enough.

Works great with on coffee warmers because of the flat bottom. Attractive, lightweight, perfect size mug highly recommended.

States that these glass mugs can be used on a cup warmer however they are so incredibly thin glass. I would be afraid to do that so I’m returning them.

These are both light and sturdy. You can put four fingers through the handle.

I love these mugs! There are light weight and elegant looking. It keeps my coffee hotter longer!

Looks great quality. Big nice size to keep sipping on my tea. I like it

Convenient, a new way of enjoying your beverages cold/hot. Very stylish.

They are very nicely balanced mugs and as resistant to heat as advertised. My only thoughts are with so much hot liquid in the glass they may be too hot to the touch for most people. That is, unless you mix the liquid with milk or don't fill the mug up or it will require two hands to hold it. Otherwise, these are really great for the price, and I do enjoy using them. They can be used for cold drinks as well, especially bee. That is one of the reasons I ordered them.

The best mug cup I’ve ever had. That’s just the right size I was looking for. Light and very good size. The others I ordered were not big enough for coffee. Really happy for my order. I highly recommend. Got compliments from my son too, he liked the cup a lot.

Happy to find tall simple shape glass mug for my regular tea.
