Sun’s Tea Double Wall Insulated Glass Tumbler, 16oz (450ml) Highball Glass Cups for Beer, Lemonade, Iced Tea, Tropical Drink, Cocktail, Smoothie, Mojito and Mixed Drinks, Set of 2 – Collins Style

Chinese beverage glasses, for hot or cold
These glasses hold around 14 ounces, and they are about 3 inches in diameter and 6 and a half inches tall (high). They are double walled, and it feels (and looks) reasonably heavy duty. They are not the fragile little glasses I have purchased before from other venders, these feel like they can take some abuse (but don’t drop them on a hard floor; they will easily break). Ok, so what’s the big deal about them? Well, they are not the most attractive glasses I have owned, but they are very utilitarian in the sense they will keep coffee hot for a long time or tea cold for a long time (or any other beverage of your choosing). My coffee will easily stay very warm for at least 20 minutes (more if you make the coffee hotter to start). I don’t like having to reheat in the microwave my coffee every 10 minutes. These glasses really do work. If you put a couple of ice cubes in a cold beverage and put it in the glass, it will stay cold for almost an hour. It is amazing. They are made in China, but I am happy with the quality (heavy duty, no noticeable flaws, well made) of these glasses. They were protectively shipped, and I got them in just a couple of days. If you wonder why they are kind of expensive (look at some of the other double walled glasses and these look cheap), it is because they are double walled, and these are thermal; that is, you can put either hot or cold liquids in them without problems. Many of the other glasses are for cold liquids only (kind of defeats the purpose of putting hot coffee in them), and one set of glasses I got had it stamped on the bottom, “do not microwave” permanently etched into the glass (or maybe somehow painted onto glass). These are now my favorite glasses for coffee, and in the late day for cold liquids (like Inkos white peach tea, so delicious). I hope this information helps!(especially the white tea plug)

Just what I wanted
I have been looking and reading reviews for these type of glasses for a while. I was tired of how quickly condensation built up on the outside of regular glasses filled with icy drinks and tired of water rings on tables when coasters were ignored. I had seen glasses made by other companies in stores and felt they might be too fragile, so decided to see if I could find sturdier ones online. I read reviews here on Amazon and decided to give these a shot as it sounded like they were what I was looking for. I ordered a set to try them out. They indeed are much sturdier than what I have seen. As others said in their reviews, the rim is thicker and it bothered some, but I figure it’s not any thicker than most coffee mugs so it doesn’t bother me. I would rather they be thicker and stronger because these type of glasses are not cheap. So if it helps it last longer than I can live with it. Time will tell as I only have had them for a couple of weeks. But I do love that they don’t condensate and ice lasts much longer. I haven’t tried hot liquids in them so don’t know how long heat lasts. I have put them in the dishwasher with no problems and even am able to fill them with ice straight from my refrigerator door. Some glass makers tell you not to do this as it can crack inner liner. This company doesn’t have that warning in fact on the box they came in it said, “passed free-fall ice ball impact test from 16 inches.” They are dishwasher and microwave safe. I decided to order more and this company gave a 10-15% discount coupon depending on order size if you order straight from them, which I did. However it took a couple of weeks to deliver where Amazon took 2 days. If you need them quickly I suggest ordering from Amazon. These glasses do come with a 6 month warranty which is good as 3 glasses in the ones I ordered from the company had a small crack on the outside bottom layer upon inspection when I opened them. I notified the company through their online warranty claim page and notified me the next day that they are sending replacements. I have to say I love these glasses and with customer service like that, I have no fear in ordering more if I need to.Update: July 29th, 2014Just to let you know I am still waiting for the replacement glasses that I was promised they were sending. The company keeps telling me they are out of stock. If you want these glasses I would definitely order through Amazon as I think Amazon has better customer service.

Just the design I was looking for so very happy. I’m using bent glass straws. A bit heavier than I expected but that does make the glass stable.

These are amazing, have bought double walled glasses in the past like Bodum which shattered within a couple of days. Super thin and fragile. Tried some stainless steel goblets which were unbreakable and well insulated but not quite the same as being able to see what you are drinking. When I opened the well packed box and held these tumblers, you can feel the difference. They are fairly heavy due to extra thick walls but feels safe & rugged in my hand. Beverages look so good and delicious inside. I love them, classy & elegant. Doesn’t quite insulate cold drinks as well as the stainless, think the walls have air inside but not in a vacuum. Can feel the cold slightly on the outside when holding it but still much better than a regular glass. Very happy with this buy.
