Are these orbs completely round or do they have a flat section where they can sit on a surface?

There is a small round flat part on the bottom, maybe 3" across, that allows it to sit still without rolling around however the flat spot is small and it's very easy to knock it over and send it tumbling so I wouldn't put it somewhere that it might be in the way.

ours are flat. Hope you don't waste your money on these mugs.....they do NOT keep coffee any warmer any longer than any other plastic mug. Is a farce!

They're flat. They have a small. Flat border at the bottom which may, from the picture, make them look flared.

The bottoms are flat. These are very cool little glasses! You won't go wrong with these.

The bottom rims are flat on the mugs. The center circle is slightly concave. We really enjoy this mugs. Well worth the money.

It is flat. If you get them, make sure to not get the water level too high. I bought this for my grandson and his beta jumped out of the opening on the top and died.

They are not rounded. This is an awesome item. Our granddaughter loves it and adults are able to sit on the very sturdy chairs to have a tea party with her. I can't say enough good things about this item. Money very well spend. She will have it for her daughter in many years to come.

They are not flat- they are kind of like bubble buttons. They stick well and there are lots to choose from!

They stay flat. Maybe if you use them a lot and incorrectly wrestle them close, they will get kinked.

It has multiple rolls of tiny squares on the underside. Yes, the underside is flat.

They are not round; they are flat from the top & almost "boat-shaped like" on the bottom so that would make them somewhat oblong. Hope that helps.

Hi, Sorry we're temp out of stock - so can't physically check but would say they're more round than flat. Hope this helps BuzzBase

yes I agree with Suzee, they are a flat top with about a quarter of an inch depth to them

They are rectangular and flat. Very little interference with placement of stuff.

The mug has an outer ring on the bottom and is then recessed about an 1/8th of an inch. . .so no, it is not a totally flat bottom surface.

Flat, yes, but with grooves. I would imagine that they would work fine on glass top surface.

So far they sit very true and flat. We learned that the secret is not to put cold water on them when they are hot. They work very well on our smooth surface stove.
