are these tumblers double-walled?

No they are not double walled, but we still like them. Safe for kids to drop yet look nicer than plastic cups.

No, they are not double-walled, but they are a very nice, solid stainless steel.

Lisa, No they're not, but they're great substitute to an ordinary drinking glass.

They are single walled and they do sweat a bit. Not as much as true glass does, though. You will want to use a coaster.

You are correct, it is not double wall insulated. As for why, I do not know, but I still love these cups!

No, but I do not believe any double walled plastic container would be. Even a Yeti stainless mug is not dishwasher safe.

Yes they are. They are very sturdy and look very good. In fact for me they are a so smooth that sometimes when i pick one up to turn it over , it is a little slippery. Like

Yes, they are as shown. With the wider lip and narrowed bottom for stacking. I have a couple from another manufacturer without this feature and these are definitely more convenient. The lids on this set seem to align better, as well.

Tumbler is double walled stainless steel. Very nice tumbler. I am very careful not to chip or scratch the white material used to beautify the outside.

These are just single wall there are some double walled ones from another company which I also like. They are more expensive of course (http://smile.amazon.com/dp/B005K96XE8/ref=sr_ph?ie=UTF8&qid;=1425057613&sr;=1&keywo;rds=double+walled+stainless). They don't stack like these do but they are great. I have tile floors and acrylic and glass done if they hit the floor. These are tough. Like i said I have both and use them regularly.

These tumblers are not designed to be stacked as their top and base are similar in diameter. Hope this answers your question.

No, they do not. Don't waste your money like I did. The seller's answer is either ignorant, or hustling to move product. These will NOT hold a cup.

I believe they are, but I have returned this product due to small pits and rust just after one use, also its very thin walled and base.

Yes they are and they are wonderful. Just don't drop! They are real glass.................. It is like an emery board that NEVER wears out!!!

Yes, it is double walled...I purchased this as a gift and the recipient was just thrilled with the size of it.

No, they are real glass, just like your normal glassware... The only difference is they're two-ply thinner glass. They will probably break sooner than they get scratches like old drinking glasses get... lol Mine seem to last about 3-4 years, then they'll drop into the sink and break, or they get tapped into the icemaker on the fridge door and break, and so on. I hand wash all my double-wall glasses, however... just to be safe and cleaner.

Yes it is double walled- I purchase it as a gift and had to ask the recipient. She has not had any issues with condensation.

No they are double walled plastic with insulation between then. The cups are black on the inside.
