Do these mugs have a completely flat bottom? Most mugs have an indented bottom so only the rim rests directly on the mug warmer.

It has a very shallow indent that goes from the center to about half way to the edge then is flat from there to the edge. I use it with a mug warmer and it keeps my coffee hot.

Are these made in USA ?

The bottom of the box clearly states that these are made in China. Perhaps the other person was confused as the box also states that they were designed in Chicago, IL. Personally, I found these way too thin to keep.

Are these microwave safe?

Thanks so much for your inquiry. Yes, the Science of Coffee Glasses 16 oz mugs are microwave safe. Please note, that like all glassware, the outside will be hot after microwaving when the glass is filled with liquid. Use the handle to hold the glass after microwaving.

Are these double wall mugs?

No but despite that they're pretty cool. I bought them like a month ago and so far so good.
