Is the interior stainless also? Or is it plastic?

It is stainless steel on the inside, for the most part. The rim is plastic, and that extends down on the inside an inch or two on the inside, but the rest is stainless steel.

it is stainless. Maybe we got a dud... but it leaked all over our son's lunchbox.

The interior is stainless. Only the cap is plastic. We really like it, it has never leaked and one goes to school with our son every day.

Yes, inside stainless. My only problem with it was it died after one year of use and some of the color chipped slightly off on the outside

It is stainless inside. I was disappointed that it wasn't black coated. I really like the latter ones so well.Apparently, they are no longer offered. If and when they ever are, I will buy several.

The exterior is stainless steel. I'm not sure if the interior is stainless because I didn't pay attention. I'll check it up tonight.

Totally stainless inside. It's super light for travel. I think it's perfect for its price.

Hi, I am also looking for one that has a stainless steel interior. Have you been able to verify that this one is stainless steel? If not, have you found one that is? Thanks!

I found that the inside was not stainless steel as advertised, and returned for credit, so I can't answer your specific question. I do hope knowing this might help you decide. It is very nice looking, however.

Yes it is. It's stainless steel on the inside and out. It's also insulated so it looks a lot thinner on the inside than outside.

I believe the interior is plastic which gives better hot & cold than stainless and does not burn hands!

The inside, bottoms and lower sides are stainless steel. It is encased in black plastic so the outside and rim of the inside are black plastic.

The inside and outside are the same, and I believe the filter is stainless steel as well. The only plastic is the black part.

I have it packed as we just moved but as I recall it's not a dark non stick interior I think it's stainless.

I would think that the interior material is plastic. The top & sides are made of plastic and the bottom is the heating element and it's metal.

Yes, it is stainless steel inside, all buttons are moving. Printing and plastic quality on the outer shell is very good as well. I would question stability though, when you have it filled with liquid, it tends to dangerously tilt, it is stable but you may end up with a mess on your desktop. Just be careful or put it away from your stuff.

The inside is stainless steel, but I would say that the finish on the inside is more like "satin" vs. polished. I hope that this is helpful
