21.75 oz. Rock Bar Stackable Super Cooler Glass, (Set of 6)

Very good quality drinking glasses. Hardy, substantial and useful.

When I set out to buy new glasses I had 3 requirements 1. Large 20oz + 2. Glass 3. Thicker and fairly durable I am absolutely thrilled with this purchase. There are very few selections for glass cups that are over 20oz. There are extremely thick and i think will be a challenge to break. They look great and they stack, which I didnt realize I would appreciate so much

Highly recommend! They are really shattered proof! These are the best glasses we have ever bought. They are dishwasher safe. They are not heavy but the glass is thick. I love that they come in 2 different sizes! They are seamless to use.

I was surprised at how quickly these arrived. They were well packaged and arrived perfectly intact. I was looking for a LARGE, well made, comfortable to hold glass, and they fit the bill--that they stack is a nice bonus. Most importantly, unlike many reviewers experience, I received the correct size glasses--a full 21.75 oz. Love them!!

Lost one star because each of the six glasses had a sticker attached that is very difficult and time consuming to remove. The stickers came off in little pieces leaving a big mess used peanut butter on glue then put in dishwasher came out clean. Made microwave hot tea in glasses added ice to hot tea in glasses no problem. They are tempered glass so they are thin but seem strong like tempered glass should be. Checked with a measuring cup almost 23 ounces filled to brim. Stack very well. Glass is Cristal clear with nice smooth edges found no bubbles or flaws. Easy to hold and drink from and don’t tip easy but bottom is smaller then top. Shipped in double custom box’s with bubble wrap between them, inside box made to fit glasses with cardboard’ separated glasses and each glass bubble wrapped. Haven’t had glasses long enough to see how well they hold up to time or what happens when dropped but when it happens I will update how tough they are. Price is good if they are quality tempted glass if not way over priced time will tell.

Nice heavy glasses

These glasses are precisely as described. No issues at all with the labels. Came right off. Made in Spain. (Not sure at all why it would matter whether they were made in Spain or Italy.) Excellent sturdy quality! We bought two smaller sizes of these glasses for my mom about five years ago and they have performed incredibly well. So, I went for the 21+ ounce version for my house because I like at least a 20 oz glass. I love the fact that, unlike most glassware, these glasses stack. Happy to get more in my cabinets!

I hope this review puts your mind at rest regarding some of the issues mentioned in other reviews. As of mid-December, 2024, this was my experience. I received six 21.75 ounce glasses as ordered in excellent condition. The thin cardboard product box lid flap was open (the locking tab was torn off), but none of the glasses were harmed, and they clearly hadn't been used. Mind you, I live very near to an Amazon warehouse -- if they have a rough time in transit, all bets are off, since there wasn't any packing material around them exept for some dog biscuits, which made up the other part of my order. The stickers on the glasses were plastic and easy to peel off, leaving no residue. A 21.75 ounce glass holds, you guessed it, 21.75 ounces when filled to the rim. Of course, you wouldn't normally fill it that full, so count on it holding 18 to 19 ounces comfortably. The glass itself weighs almost exactly one pound, but the ergonomics are such that it is comfortable to hold and doesn't feel unduly heavy, at least not to me. It's big, so you expect it to be heavy and the body adjusts. (I've found some 12-ounce Libbey Duratuff Gibraltar glasses to be subjectively too heavy because they are much smaller, and you aren't expecting the weight of the thick glass.) You don't have to grip the glass tightly because the wider top keeps it from slipping out of your hand. Yes, the glasses were made in Spain. I didn't find any bubbles, wrinkles or unevennesses in the glass. They are attractive and delightful for smoothies. They'd probably be grand for iced tea, too, but since it's December, I haven't checked that out. They stack nicely, but you need a shelf with enough height to accommodate them. One glass is 6.5 inches tall, and a stack of two glasses is 9 inches tall. They are about 3.75 inches in diameter at the rim and 2.5 inches at the 9-sided base. Hope this helps!

Was looking for a good set of drinking glasses. Tired of having to refill smaller glasses. These hold a good quantity of whatever you’re drinking. Very nice quality and heavy feel to them. Had them for about 2 months now and no issues at all. Very durable and will last a long while. Highly recommended!

these glasses are great value, very sturdy, stack inside each other for the cupboard. very nice shape and they come in different sizes. great value for money.

These glasses are sturdy, fit nice into your hand, wash nicely in a dishwasher and look nice as well. They are of high quality from what I can see and so far no problems! They may be higher priced however the quality is worth it.

TL;DR These glasses are so big, they can be filled half way with ice and still fit a can of your favourite pop/soda/coke! I definitely recommend them. I purchased these glasses a year or two ago and they've have been great! They're large and feel very sturdy. They have some weight to them (not too heavy) but I would advise caution when used by small children as their size and weight may make it difficult to handle with small hands. It does taper as it gets to the bottom of the glass so maybe it won't be a problem (use your own discretion). I saw some other reviewers state they received the 16oz version instead of the larger ~21oz; I got the correct size, but maybe I was lucky that I didn't get shipped the wrong ones. I've had issues with other items in the past, and Amazon has always been easy to deal with to get the problem resolved so I wouldn't hesitate to purchase them again.

Arrived with lots of scratches and marks and micro bubbles within the glass itself. I tried to take a picture, but can’t seem to get a picture to capture the scratch marks. Other than that, I love the glass. They’re not too heavy and they are big enough. Amazon did give me a substantial rebate so I will keep them. However, I would not keep them without the rebate because it is a lot of money to spend on every glass when there are scratched up like that.
